Top having a loading aid function and convertible vehicle having such a top

Abstract

A top for a convertible vehicle, having a top cover and a top linkage which can be displaced between a covering position and a storage position, in which the vehicle interior is open at the top, and which may have a link assembly on either side of a vertical longitudinal center plane of the top, the top linkage having a corner bow which extends in the transverse direction of the vehicle and which defines an area of transition of the top cover between a roof portion and a rear portion when the top linkage is in the covering position. When the top linkage is in the covering position, the corner bow is secured against pivoting by means of at least one blocking element disposed on a pivoting part of the top linkage and can be displaced from the covering position into a loading position by displacing the pivoting part.

DETAILED DESCRIPTION

(13) FIG. 1 shows a convertible vehicle 10 which is an off-road vehicle. Convertible vehicle 10 comprises a vehicle body 62, which surrounds a vehicle interior, and a displaceable top 12. When in a covering position, which is illustrated in FIGS. 1, 2, 3 and 5 and in which the vehicle interior is covered, top 12, which is a folding top, extends from a front header 64, which forms an upper leg of a windshield frame extending in the transverse direction of the vehicle, into a rear portion 66.

(14) Top 12 comprises a top cover 14 which can be displaced by means of a top linkage 19. Top linkage 19 can be displaced between the covering position and a storage position, which is illustrated in FIGS. 4 and 8 and in which the vehicle interior is open at the top and top 12 is stored in a rear storage space of vehicle body 62. Moreover, top 12 can be displaced from the covering position into a loading position, which is illustrated in FIGS. 9 and 12 and in which a cargo space of vehicle 10 is easily accessible.

(15) Top linkage 19 comprises a link assembly 20 on either side of a vertical longitudinal center plane of the top. Link assemblies 20 are mirror-symmetrical with respect to the longitudinal center plane of the vehicle, which is why, for the sake of clarity, only link assembly 20 on the left with respect to the direction of forward travel of vehicle 10 will be explained in detail below.

(16) Link assemblies 20 each comprise a four-bar linkage having a first main link 22, a second main link 24, and a coupling link 26 connecting first main link 22 and second main link 24.

(17) First main link 22 is L-shaped and comprises a long leg 22a and a short leg 22b. In the covering position, long leg 22a extends in the longitudinal direction of the vehicle and short leg 22b extends in the vertical direction of the vehicle, coupling link 26 extending approximately parallel to long leg 22a of first main link 22.

(18) In the covering position, long legs 22a of first main links 22 of link assemblies 20 each form a roof side beam which has a weather strip and whose front end reaches or comes close to front header 64 of convertible vehicle 10. A front bow 32 is rigidly attached in the front end portion of long legs 22a, said front bow 32 extending in the transverse direction of the vehicle between both link assemblies 20 disposed on either side of the vertical longitudinal center plane of the top.

(19) Short leg 22b of main link 22 is pivotably mounted on a respective vehicle-attached main bearing 16 via a hinge point 52. A driving element in the form of a gas pressure spring 70 is articulated to a side of short leg 22b that faces the vehicle interior, said gas pressure spring 70 aiding displacement of top 12. A first end of gas pressure spring 70 engages first main link 22 and the other end is supported on vehicle-attached main bearing 16.

(20) As top 12 is being displaced from the covering position into the storage position, gas pressure springs 70 of both link assemblies 20 at first each aid pivoting of respective first main link 22 in the direction of the vehicle rear until an intermediate position is reached. When first main links 22 are then pivoted further, displacement of top linkage 19 is damped by gas pressure springs 70, allowing the storage position to be reached without top linkage 19 crashing onto the vehicle body.

(21) Second main links 24 of link assemblies 20 are each pivotably mounted on respective vehicle-attached main bearing 16 in a hinge point 54. At their ends located at the top when in the covering position, second main links 24 are each pivotably connected to respective coupling link 26.

(22) Furthermore, top linkage 19 comprises three tube-like transverse bows 34, 36 and 38 and a tube-like corner bow 40, which extend in the transverse direction of the roof and across which top cover 14 is stretched (tensioned) in the covering position. Transverse bows 34, 36 and 38 and corner bow 40 connect mirror-symmetrical link assemblies 20 and are pivotably mounted.

(23) Transverse bow 34 is rigidly attached to a bow link 42 at both sides, said bow link 42 and a respective control link 28 and respective coupling link 26 together forming a four-bar linkage, bow link 42 pivotably connecting control link 28 and coupling link 26. Control link 28 is pivotably mounted on first main link 22 of respective link assembly 20.

(24) Transverse bow 36 is rigidly attached to second main links 24 at both sides, in particular to the ends of second main links 24 located at the top when in the covering position. Transverse bow 38 and corner bow 40 are each rigidly attached to bow links 44 and 46, respectively, and connected to second main links 24 via said bow links 44 and 46.

(25) When top linkage 19 is in the covering position, corner bow 40 defines an area of transition of top cover 14 between a roof portion 68, which extends in the longitudinal direction of the vehicle, and rear portion 66, which extends in the vertical direction of the vehicle.

(26) A tensioning bow 50 is pivotably mounted on vehicle-attached main bearings 16 disposed on either side of the longitudinal center plane of the vehicle. Tensioning bow 50, which surrounds the vehicle interior of vehicle 10 at the rear at the height of a beltline surrounding a cargo space, comprises two legs 50a which extend in the longitudinal direction of the vehicle when in the covering position and via which tensioning bow 50 is pivotably mounted on vehicle-attached main bearings 16. Both legs 50a are connected via a transverse beam 50b, which extends in the transverse direction of the vehicle.

(27) A blocking element 18 is disposed on a side of each leg 50a of tensioning bow 50 that faces the longitudinal center plane of the vehicle. Blocking element 18 is a stop element having a nose-like protrusion and is screwed or riveted to respective leg 50a of tensioning bow 50.

(28) In FIGS. 10 to 12, the rear area (in the longitudinal direction of the vehicle) of left link assembly 20 (with respect to the forward direction of travel of vehicle 10) is illustrated in detail in different covering positions.

(29) In FIG. 10, top linkage 19 is in its covering position, blocking elements 18 or protrusions of blocking elements 18 disposed on tensioning bow 50 securing bow link 46 against unintentional displacement in the direction of the front of the vehicle and in the vertical direction of the vehicle. Otherwise, unintentional displacement of this kind could be caused by a fabric tension of top cover 14.

(30) When the top is being displaced into the loading position as illustrated in FIGS. 9 and 12, tensioning bow 50 is lifted, causing blocking elements 18 to be removed from bow links 46, thus releasing them, so that bow links 46 and thus corner bow 40 can also be pivoted forward in the direction of the vehicle front. This displacement takes place manually.
