Definitions
- the invention relates to a roof arrangement for a convertible with a rigid front roof part and a rigid rear part, in which the rear part is swung over the front roof part and the two roof parts are lowered as a package into a rear storage compartment for the roof.
- German Patent DE 44 35 222 C1 and corresponding U.S. Pat. No. 5,769,483 show a roof arrangement for a convertible in which the rear part of the roof arrangement is swung over a front roof part and then the stacked roof parts are lowered rearwardly into a rear storage compartment for the roof.
- This way of stacking the front roof part and the rear part on top of one another, the two roof components coming to rest on top of one another in the same direction with respect to their arched curvature, has the advantage that the roof parts stacked into a package are arranged in a very space-saving manner and therefore require less space in the rear stowage space of the motor vehicle.
- a mechanism in which a triangular lever is coupled to the body and can be driven via a drive cylinder. Between the triangular lever and the rear part there are two hydraulic cylinders and one telescoping guide. Furthermore, there is a pivot lever which, on the one hand, is coupled in the rear area of the body, and on the other hand, is connected to the rear end section of the roof part.
- the multi-joint is formed, here, by one of the two hydraulic cylinders, a triangular lever, a drive cylinder and the pivoting lever.
- One of the two hydraulic cylinders must be released in this pivoting motion in order not to prevent pivoting motion into the stowage space because the two hydraulic cylinders, together with the pivoting lever, would otherwise represent a mechanical redundancy.
- the two hydraulic cylinders, together with the triangular lever and the drive cylinder therefore, represent a multi-joint connection between the roof arrangement and the body.
- the rear part is coupled to the body via a four-bar mechanism with two levers. Since the rear part is swung by driving the four-bar mechanism over the roof part and is interlocked with the roof part, the stacked roof arrangement is swung to the rear into the storage compartment for the folding roof via the two levers of the four-bar mechanism and the other pivoting lever which is coupled between the roof part and the body.
- This arrangement of three levers between the stacked roof arrangement and the body represents a mechanical redundancy in which a pivoting motion is only possible when either a certain arrangement of the levers is chosen or one of the levers is detachably coupled during certain phases of motion.
- an object of this invention is to devise a roof arrangement of the initially described type in which the inherently complex sequence of motions for opening and closing the roof arrangement is achieved by a simple mechanism with as few drive units as possible.
- a forced control mechanism has a single lever which is located between the rear roof part and the rear body and which is connected at one end via a first pivot joint to the rear roof part and is coupled at another end to the body.
- this approach calls for the fact that, to open the roof arrangement, first the rear part is swung over the front roof part and then the front roof part together with the rear roof part stacked over it are swung into the storage compartment for the folding roof, the forced control mechanism having a single lever which is located between the front roof part and the rear roof part and which is connected at one end, via the first pivot joint, to the rear part and is coupled at the other end to the body.
- the first pivot joint is located in the line of gravity of the rear part.
- the rear part can be easily swung over the roof part.
- the rear part can be folded out especially advantageously by a guide means between the rear section of the front roof part and the top section of the rear part.
- the guide means has the advantage that the top end section of the rear part can be guided very closely and accurately with little mechanical effort over the rear section of the front roof part.
- the end section of the lever coupled to the body has an inner mounting point and an outer mounting point which is spaced away from the inner mounting point, and they can be selectively connected via a switching means either to a second pivot bearing or to a third pivot bearing.
- a switching means either to a second pivot bearing or to a third pivot bearing.
- the switching means for reversing from the connection of the inner mounting point to the second pivot bearing to the connection of the outer mounting point to the third pivot bearing and vice versa has a locking mechanism, the lock being guided via a crank and the lifting cylinder being connected to the lever via the lock such that the lifting cylinder also drives the lock motion.
- the special advantage of this arrangement is that the lifting cylinder, during the switching process, does not cause any motion of the roof arrangement so that, simultaneously with the switching process, the rear part can be interlocked with the roof part in the stacked arrangement and the roof part with the windshield can be unlocked. In this way, also a precision transition from swinging up the rear part to lowering of the stacked roof arrangement is also possible without the lifting cylinder having to change its speed.
- the lifting cylinder can rather easily move from one end position to the other end position with a constant speed.

Abstract
Description
- 1. Field of the Invention
- [0001] The invention relates to a roof arrangement for a convertible with a rigid front roof part and a rigid rear part, in which the rear part is swung over the front roof part and the two roof parts are lowered as a package into a rear storage compartment for the roof.
- 2. Description of Related Art
- [0002] German Patent DE 44 35 222 C1 and corresponding U.S. Pat. No. 5,769,483 show a roof arrangement for a convertible in which the rear part of the roof arrangement is swung over a front roof part and then the stacked roof parts are lowered rearwardly into a rear storage compartment for the roof. This way of stacking the front roof part and the rear part on top of one another, the two roof components coming to rest on top of one another in the same direction with respect to their arched curvature, has the advantage that the roof parts stacked into a package are arranged in a very space-saving manner and therefore require less space in the rear stowage space of the motor vehicle. To stack the roof parts on top of one another and to lower them into the rear stowage space or the storage compartment for the folding roof, in one embodiment, there is a mechanism in which a triangular lever is coupled to the body and can be driven via a drive cylinder. Between the triangular lever and the rear part there are two hydraulic cylinders and one telescoping guide. Furthermore, there is a pivot lever which, on the one hand, is coupled in the rear area of the body, and on the other hand, is connected to the rear end section of the roof part. When the roof arrangement is opened, first the rear part is moved radially outward by extending the two hydraulic cylinders and then the rear part is swung up over the roof part by a special locking means. At this point, the drive cylinder is retracted again, the roof arrangement being swung around a multi-joint to the rear into the stowage space. The multi-joint is formed, here, by one of the two hydraulic cylinders, a triangular lever, a drive cylinder and the pivoting lever. One of the two hydraulic cylinders must be released in this pivoting motion in order not to prevent pivoting motion into the stowage space because the two hydraulic cylinders, together with the pivoting lever, would otherwise represent a mechanical redundancy. The two hydraulic cylinders, together with the triangular lever and the drive cylinder, therefore, represent a multi-joint connection between the roof arrangement and the body.
- [0003] In another embodiment, the rear part is coupled to the body via a four-bar mechanism with two levers. Since the rear part is swung by driving the four-bar mechanism over the roof part and is interlocked with the roof part, the stacked roof arrangement is swung to the rear into the storage compartment for the folding roof via the two levers of the four-bar mechanism and the other pivoting lever which is coupled between the roof part and the body. This arrangement of three levers between the stacked roof arrangement and the body represents a mechanical redundancy in which a pivoting motion is only possible when either a certain arrangement of the levers is chosen or one of the levers is detachably coupled during certain phases of motion.
- [0004] The mechanical embodiments shown in German Patent DE 44 35 222 C1 and corresponding U.S. Pat. No. 5,769,483 are accordingly made very complex, and a host of drives is necessary to execute the motion for opening and closing the roof arrangement.
- [0005] Therefore, an object of this invention is to devise a roof arrangement of the initially described type in which the inherently complex sequence of motions for opening and closing the roof arrangement is achieved by a simple mechanism with as few drive units as possible.
- [0006] This object is achieved by a roof arrangement in which a forced control mechanism has a single lever which is located between the rear roof part and the rear body and which is connected at one end via a first pivot joint to the rear roof part and is coupled at another end to the body. For a convertible with a rigid front roof part, a rigid rear part and a storage compartment for the folding top located in the rear area of the vehicle for holding the roof arrangement and a forced control mechanism for opening and closing the roof arrangement, this approach calls for the fact that, to open the roof arrangement, first the rear part is swung over the front roof part and then the front roof part together with the rear roof part stacked over it are swung into the storage compartment for the folding roof, the forced control mechanism having a single lever which is located between the front roof part and the rear roof part and which is connected at one end, via the first pivot joint, to the rear part and is coupled at the other end to the body.
- [0007] By providing a single lever between the rear part and the body, a simple mechanism is provided which, on the one hand, allows the rear part to be easily swung up over the front roof part, and on the other hand, after pivoting up, additional connecting levers need not be unlocked to enable pivoting of the entire stacked roof arrangement into the storage compartment for the folding roof.
- [0008] In one embodiment, the first pivot joint is located in the line of gravity of the rear part. In this way, the rear part can be easily swung over the roof part. The rear part can be folded out especially advantageously by a guide means between the rear section of the front roof part and the top section of the rear part. The guide means has the advantage that the top end section of the rear part can be guided very closely and accurately with little mechanical effort over the rear section of the front roof part.
- [0009] In one embodiment, the end section of the lever coupled to the body has an inner mounting point and an outer mounting point which is spaced away from the inner mounting point, and they can be selectively connected via a switching means either to a second pivot bearing or to a third pivot bearing. In this way, it is advantageously possible, on the one hand, to optimally fix the coupling point for pivoting up the rear part, and on the other hand, to optimally fix the coupling point for lowering the stacked roof arrangement for the lever. Furthermore, when using a lifting cylinder as the drive for the lever, the direction of rotation of the lever can be advantageously reversed at the same time with reversing from the one to the other pivot joint when the lifting cylinder is coupled between the inner and the outer mounting point.
- [0010] In one advantageous embodiment, the switching means for reversing from the connection of the inner mounting point to the second pivot bearing to the connection of the outer mounting point to the third pivot bearing and vice versa has a locking mechanism, the lock being guided via a crank and the lifting cylinder being connected to the lever via the lock such that the lifting cylinder also drives the lock motion. The special advantage of this arrangement is that the lifting cylinder, during the switching process, does not cause any motion of the roof arrangement so that, simultaneously with the switching process, the rear part can be interlocked with the roof part in the stacked arrangement and the roof part with the windshield can be unlocked. In this way, also a precision transition from swinging up the rear part to lowering of the stacked roof arrangement is also possible without the lifting cylinder having to change its speed. The lifting cylinder can rather easily move from one end position to the other end position with a constant speed.
- [0011] Preferred embodiments of the invention are described below with reference to the drawings.

- [0017] In FIGS. 1 & 2, a convertible1 has a
body 2 with aroof arrangement 3 is composed of multiple parts that form a convertible vehicle roof which can be inserted as a roof module into thebody 2. - [0018] The
roof arrangement 3 has arear part 4 and afront roof part 5 which is arranged essentially horizontally and the front end section of which is detachably connected to the top transverse member (apron) 8 of thewindshield 11 via a lock mechanism 13 (shown only schematically). [0019] As shown in FIG. 3, the rear end section of thefront roof part 5 is connected at each lateral side to thebody 2 via arespective pivoting lever 15.Pivoting lever 15 is connected via apivot joint 17 to theback end section 7 of theroof part 5 and via apivot joint 19 to thebody 2. Thepivot joint 19 is located laterally in the rear area behind abackrest 21 of therear seat 23, roughly at half the height of thebackrest 21. Thepivoting lever 15 is C-shaped and is configured such that it is held by theside member 25 of therear roof part 4. Therear roof part 5 together with the side pivoting levers 15, which assume the function of the C column, form a roll cage for the motor vehicle 1. - [0020] Between the
back end section 7 of thefront roof part 5 and the rear area of the vehicle body is the rigidrear roof part 4 which drops away obliquely to the rear and which is provided with a rear window 27. Thelower section 29 of therear roof part 4 sits on therear hatch 31, forming a seal. Under therear hatch 31 is astorage compartment 33 for storing the loweredroof arrangement 3. Thestorage compartment 33 is used, at the same time, as thetrunk space 35. Therear hatch 31 can be swung up via the rear axis of rotation 37 (shown only schematically in FIG. 3) to the rear to enable access to thestorage compartment 33 and therear hatch 31 can be swung up around afront axis 39 of rotation (also shown only schematically in FIG. 3) to the front in order to enable access to thetrunk 35. - [0021] The
roof part 5, on the front end section adjacent to thecross beam 8 of thewindshield 11, has acover 41 which can be pushed to the rear in the manner of a conventional sliding sunroof over the rear part of thefront roof part 5 so that, with thecover 41 opened, a roughlyrectangular opening 43 is formed in the front area of thefront roof part 5. The opening 43 is bounded on each side by a post-likeside roof part 45. Alock mechanism 13 for connecting theside roof parts 45 to thecross beam member 8 is located in the front end section of eachside roof part 45. - [0022] Instead of making the
cover 41 as a sliding roof which is guided outwardly over theroof skin 47 of theroof part 5, thecover 41 can also be made as a sliding and lifting roof which is moved down and under theroof skin 47 of thefront roof part 5. Furthermore, thecover 41 can also be formed as a sliding roof formed of a host of louvers which can be pushed to the rear. - [0023] In the following, the structure of the forced
control mechanism 49 is explained with reference to FIGS. 3 & 4. The forcedcontrol mechanism 49, which includes the already mentionedpivoting lever 15, is located on both sides of thebody 2 in an area laterally relative to thebackrest 21 of theback seat 23. The forcedcontrol mechanism 49 is used to swing therear roof part 4 over thefront roof part 5 and locks to theroof part 5 via a locking means 51 in that position, and afterwards, swings the resultingroof package 53 to the rear into thestorage compartment 33. - [0024] The forced
control mechanism 49 has a Z-shapedlever 55 which, with theroof arrangement 3 closed (FIG. 3), has a horizontally arrangedmiddle section 57, arear section 59 and afront leg 61. Themiddle section 57 is located underneath the sidetop body edge 63. Therear leg 59 extends up into theside beam 25 of therear part 4 and is mounted on itsend section 65 via a first pivot joint 67 to therear part 4 in the area of the line of gravity of therear part 4. Thefront leg 61 extends down into theside body 2. A brace 69, which is located obliquely between thefront leg 61 and themiddle section 57, is used to strengthen thelever 55. On the transition area between themiddle section 57 and thefront leg 61, there is an inner mounting point 71 on thefront leg 61 with which thelever 55 can be connected via a second pivot joint 73 to thebody 2. On the lower end side of thefront leg 61, there is anouter mounting point 75 with which thelever 55 can be connected to thebody 2 via a third pivot joint 77. In the position shown in FIG. 3 with theclosed roof arrangement 3, thelever 55 is connected by its inner mounting point 71 to the second pivot joint 73. The third pivot joint 77 is located behind and underneath the second pivot joint 73 at a distance which corresponds to the distance between the inner and the outer mounting points 71 and 75. - [0025] In FIGS. 3 & 4, there is a switching means79 in the
front leg 61. With this switching means 70, the connection of the inner mounting point 71 to the second pivot joint 73 can be released and the connection of theouter mounting point 75 to the third pivot joint 77 can be established, and vice versa, when thelever 55 is in a position (see FIG. 6) in which, at the same time, the inner mounting point 71 of thelever 55 engages the second pivot joint 73 and theouter mounting point 75 engages the third pivot joint 77. Reversal takes place in this position by locking either the inner or theouter mounting point 71, 75 to the pivot joint 73, 77, respectively. - [0026] For this purposes, the switching means79 has a sliding
bolt 81 which is supported to be pushed back and forth between the two mountingpoints 71, 75 in thefront leg 61, which is made as a rectangular tube. The position of the slidingbolt 81 is controlled by aguide track 83 as is described below. - [0027] In the middle section of the
front leg 61, in the side walls of thefront leg 61, aopening 85 is formed through which apin 87 which is attached to the slidingbolt 81 extends on either side of thefront leg 61. On thepin 87, via a fourth pivot joint 89, a liftingcylinder 91, which is made in the form of a hydraulic cylinder, is connected to the front end of its piston rod. The liftingcylinder 91 in FIG. 3 is positioned roughly horizontally and is connected at its other end to therear body 2 via a fifth pivot joint 92. The liftingcylinder 91 is used as the main drive for the forcedcontrol mechanism 49. On both end of thepin 87 there is aroller 93, each of which is guided to follow the path 94 of theguide track 83 which partially surrounds theroller 93. - [0028] The second pivot joint73 has a pin 95 which is attached to the
body 2 and which can fit into aU-shaped opening 96 which is pointed forward and which is made on the inner mounting point 71 of thelever 55. The third pivot joint 77 has a pin 97 which is attached to thebody 2 and which can fit into aU-shaped opening 98 which is pointed to the rear and which is made on theouter mounting point 75. The slidingbolt 81 has a top fork 99 on its top end and alower fork 100 on its bottom end, which open to the respective end. In FIG. 3, theU-shaped opening 96 of the inner mounting point 71 engages the pin 95 of the second pivot joint 73 and the slidingbolt 81 is pushed towards the inner mounting point 71, its top fork 99 surrounding the pin 95, thus locking thelever 55 with its inner mounting point 71 to the second pivot joint 73. In this position, the oppositeouter mounting point 75 is in the unlocked position so that theU-shaped opening 98, which is pointed to the rear, can be engaged with the pin 97 of the third pivot joint 77. - [0029] The path94 of the
guide track 83 is fixed on the body, is arranged essentially horizontally, and has three sections, a circularfront path section 101, a straight middle path section 103 and an arcuaterear path section 105. Thefront path section 101 has its middle point in the pin 95 of the second pivot joint 73, the radius of the circle being chosen such that the slidingbolt 81 is held in the locking position for locking the inner mounting point 71 to the second pivot joint 73. The rotary angle of thefront path section 101 corresponds to the angular distance which must be traversed by thelever 55 when turning counterclockwise around the second pivot joint 73 to swing therear part 4 from the lower closed position of theroof arrangement 3 into the position over theroof part 5. Thefront path section 101 is adjoined by the middle path section 103 which runs as a straight line between the pin 95 of the second pivot joint 73 and the pin 97 of the third pivot joint 77, the length of the middle path section corresponding to the path traversed by the slidingbolt 81 from an inner locking position to an outer locking position. Therear path section 105 which adjoins the middle path section 103 has its midpoint in the pin 97 of the third pivot joint 77, the radius of the circle being chosen such that the slidingbolt 81 can be kept in the locking position for locking of theouter mounting point 75 to the third pivot joint 77. The angle of rotation of therear path section 105 corresponds to the angular path which must be traversed by thelever 55 when turning clockwise around the third pivot joint 77 in order to swing thefront roof part 5, with therear roof part 4 located over it, into therear storage compartment 33 for the folding roof. - [0030] Between the
upper end section 30 of therear part 4 and therear end section 7 of theroof part 5, on both sides of the vehicle, there is arespective guide mechanism 107 with which theupper end section 30 of therear part 4 is guided in theroof part 5 during pivoting motion over the roof part 5 (FIGS. 5 to 8). Theguide mechanism 107 has a L-shaped slide lever 109 which has one long leg 111 and oneshort leg 113. The long leg 111 is coupled via an eighth pivot joint 115 to thetop end section 30 of therear part 4, and with theroof arrangement 3 closed it is located essentially horizontally. Theshort leg 113 is guided in aslide rail 117 which is made in the direction of travel laterally on the roof part 5 (shown only schematically). Theslide rail 117 which is preferably located in a groove in theroof part 4 and which is aligned parallel to theroof skin 47 in the rear end section, has asection 119 which is curved down to enable pivoting of the long leg 111 from the horizontal position into the vertical position around theshort leg 113 which is used as the pivot joint and vice versa. The motion of the slide lever 109 takes place depending on the motion of therear part 4 relative to theroof part 5. - [0031] Instead of providing a guide mechanism, on the first pivot joint67 between the
lever 55 and therear part 4, there can also be a rotary drive with which therear part 4 can be swung around the first pivot joint 67 when pivoting up over theroof part 5 relative to thelever 55. - [0032] The locking means51 (shown only schematically) is located between the
roof part 5 and therear part 4 in order to securely lock therear part 4 on theroof part 5 after it has been swung over theroof part 5, so that theroof part 5 and therear part 4 form aroof package unit 53. The locking means 51 can also be designed to lock therear end section 8 of theroof part 5 to theupper end section 30 of therear part 4 with theroof arrangement 3 closed in order to stabilize theroof arrangement 3 in the closed position. - [0033] In the following, the operation of opening and closing the
roof arrangement 3 is explained with reference to FIG. 3 and FIGS. 5 to 9. FIG. 3 shows theroof arrangement 3 in the closed position and at this point it can be transferred into the opened position via the forcedcontrol mechanism 49. For the case in which there is locking of therear part 4 to theroof part 5 and/or to the rear area of thebody 2, this locking must first be released. In this initial situation, thelever 55 is connected by its inner mounting point 71 via the second pivot joint 73 to thebody 2. The liftingcylinder 91 is moved in the direction of thearrow 123 so that thelever 55 turns counterclockwise around the second pivot joint 73. Therear part 4 is initially raised up vertically by the arrangement of the second pivot joint 73 and thelever 55. The slide lever 109 of the guide means 107 swings around the eighth pivot joint 115 and around theshort leg 113 so that thetop end section 30 of therear part 4 is raised over theback end section 8 of the roof part 5 (FIG. 6). The liftingcylinder 91 continues to swing thelever 55 until therear part 4 is positioned completely over theroof part 5 adjacent to theroof skin 47, thetop end section 30 of therear part 4 being guided via theslide rail 117 of the guide means 107 along theroof part 5. - [0034] Before, during or after pivoting of the
rear part 4 over theroof part 5 thecover 41 can be pushed to the rear to expose theU-shaped opening 43. Thecover 41 comes to rest between theroof skin 47 and the rear part 44. This arrangement has the advantage that the headroom in the interior is greater than for acover 41 which is pushed to under theroof skin 47 for opening. - [0035] As soon as the
rear part 4 is lifted far enough from the front end section of therear hatch 31, the latter can be opened about therear axis 37 of rotation, upward to the rear so that thestorage compartment 33 for the folding top becomes accessible for lowering theroof arrangement 3. - [0036] If the
rear part 4 is located over the roof part 6, theroller 93 must traverse the circularfront path section 101 of thecrank 83. In this position, theU-shaped opening 98 of theouter mounting point 75 of thelever 55 engages the pin 97 of the third pivot joint 77. The continuing motion of the lifting cylinder along the straight middle path section 103 of thecrank 83 pushes the slidingbolt 81 to the pin 97 of the third pivot joint 77, the locking of the inner mounting point 71 to the second pivot joint 73 being released, and at the same time, locking of theouter mounting point 75 to the third pivot joint 77 being effected. During this reversing process, no parts of theroof arrangement 3 are moved. In this interrupted motion, for theroof arrangement 3, on the one hand, therear part 4 can be interlocked to theroof part 5 in the position stacked on top of one another by the locking means 121, and on the other hand, theside roof parts 45 can be released from the upper cross member 9 of thewindshield 11 via thelock mechanism 13. - [0037] After completion of the switching process, the
lever 55 is unlocked from the second pivot joint 73 and is interlocked to the third pivot joint 77. By the continuing motion of the liftingcylinder 91, theroller 93 now reaches therear path section 105 of thecrank 83. Thelever 55, at this point, begins to turn clockwise around the third pivot joint 77, thelever 55 and the pivotinglever 15 forming a four-bar mechanisms between theroof arrangement 3 and thebody 2. The first pivot joint 67 is now located in the rear area of thefront roof part 5 over it, the first pivot joint 67 being located in front of and above the sixth pivot joint 17. In the rear area of the body, the third pivot joint 77 is likewise located in front of and above the seventh pivot joint 19, the distance between the first pivot joint 67 and the third pivot joint 77 roughly corresponding to the distance between the sixth pivot joint 17 and the seventh pivot joint 19 so that the four-bar mechanism is made almost as a parallelogram. - [0038] Therefore, upon further movement of the lifting cylinder91 (FIGS. 7 to 9) the
entire roof arrangement 3 is swung into therear storage compartment 33. In doing so, theside roof parts 45 are lowered into theside body 2 next to theback seats 23 so that theU-shaped opening 43 surrounds theback seats 23, the top of theside roof parts 45, moreover, being used as the cover for theside body 2. At this point, therear hatch 31 can again be closed around therear axis 37 of rotation, therear hatch 37 covering the area behind therear seats 23. If theroof arrangement 3 is located in thestorage compartment 33, theroller 93 must traverse therear path section 105 of thecrank 83. - [0039] The closing process of the
roof arrangement 3 proceeds in the reverse sequence. - [0040] It should be noted as especially advantageous in the switching of the body-side end of the
lever 55 from the second pivot joint 73 to the third pivot joint 77 that the third pivot joint 77 is located behind the second pivot joint 73 such that theroof arrangement 3 stacked on top of one another can be swung with thesame lever 55 further into the rear area of the vehicle 1. - [0041] It is furthermore advantageous in this arrangement that that only one
lever 55 is necessary for pivoting up therear part 4 over theroof part 5, thesame lever 55 also executing the lowering motion together with the pivotinglever 15. It should be noted as especially advantageous that, aside from the locking mechanisms and the motion of the rear hatch, the entire operation of opening and closing theroof arrangement 3 takes place by a drive in the form of alifting cylinder 91. - [0042] The invention can also be used for a
roof arrangement 3 without amovable cover 41 when thefront roof part 5 is correspondingly short, for example, in a two-seater vehicle 1. - [0043] Furthermore, the
side roof parts 45 can also be made to swing so that theside roof parts 45 are swung about a vertical axis of rotation towards the center of the U-shaped recess.
