Description

The invention relates to the arrangement and design of a tolerance compensation element for tolerance compensation on the receiving side of a removable vehicle seat or a removable bench.

When installing vehicle seats, care must be taken to ensure that the vehicle seat sits firmly in the receptacle in relation to a receptacle after the vehicle seat has been secured by locking and unlocking using a locking and unlocking device so that there is play between the components that move relative to one another when driving is avoided. A vehicle seat or bench that moves relative to the holder can quickly lead to undesirable noises in the respective storage area.

Various writings address this problem. For example, this describes DE 38 31 101 C2 , the DE 101 15 243 B4 and the DE 196 35 470 A1 Fastening or storage devices for vehicle seats, in which tolerance compensation of the components that move relative to one another is carried out.

However, these solutions are not suitable for removable vehicle seats or bench seats, in particular 1/3 to 2/3 split rear bench seats, which can be locked on individual seat feet in a body-side receptacle. Due to the respective manufacturing tolerances of the components assembled in the installed state, such as the body-side receptacle, the respective seat base or the seat feet and the locking and unlocking device arranged in or on the receptacle, undesirable play can occur when arranging the vehicle seat in the body-side receptacle .

It will also be on the printed matter DE 10 2005 024 816 A1 ; DE 10 2004 047 455 A1 ; DE 199 15 136 A1 ; and DE 299 12 439 U1 refer to the relevant state of the art.

In particular, tolerances in the vertical direction (z-direction) are to be expected, since due to the manufacturing tolerances and due to the possible removal of the vehicle seat in the z-direction, after the vehicle seat has been installed and locked via the locking and unlocking device that prevents removal, there is play in the vehicle seat compared to the locking and unlocking device, as a result of which the vehicle seat is not sufficiently fixed in the body-side receptacle in the z direction and may cause rattling noises when driving. This undesirable game is intended to be avoided by the invention.

The invention is therefore based on the object of arranging a removable seat, in particular a vehicle seat, in particular a removable one-part or multi-part bench seat on a body in such a way that manufacturing tolerances are tolerable, so that when installed, a tight fit of the components is always ensured, at least largely without play.

To solve the problem, at least one tolerance compensation element is provided, which is arranged within a fastening unit of a removable seat, in particular a one-part or multi-part removable bench, the fastening unit comprising seat feet which, when the seat is installed, are located in receptacles fixed to the body via a locking and unlocking device Vertical direction (z-direction) are locked, the play in the z-direction present in the installed state of the seat being compensated for by at least one tolerance compensation element supported on the body.

According to the invention, it is provided that any play in the z direction that may be present in the installed state is compensated for by the tolerance compensation element which is supported on the body, which in a first embodiment is integrated into the receptacle between the seat feet and the receptacle fixed to the body or which, in a second embodiment, is integrated into the receptacle the seat feet are arranged integrated.

According to the invention, it is provided in detail that, according to a first embodiment, the tolerance compensation element is integrated into the body-fixed receptacle and is arranged between the seat feet and the body-fixed receptacle, the tolerance compensation element being a cover element that can be fastened on the receptacle and for receiving the seat feet in the installed state of the Seat has elastically deformable damping tongues that are lower in the vertical direction compared to an upper edge of the receptacle, each of which has at least one damping nub on its underside on the body side, whereby the damping tongues are elastically deformable over the respective damping nub, compensating for the play in the vertical direction, forming a spring element-like Support the restoring force on the body.

According to a second embodiment, the invention provides in detail that the tolerance compensation element is arranged integrated into the seat feet, the tolerance compensation element being a support element that can be fastened in a seat foot ment, which houses a damping block which is held on the support element via a cover element, the support element being arranged to be movable relative to the cover element in a common locking step in the installed state of the seat, whereby the support element moves over the respective elastically deformable damping block, compensating for the play in the vertical direction, by building up a spring element-like restoring force via the cover element on the body.

The invention makes it possible, for example, to design a relatively large and heavy 2/3 part of a 1/3 to 2/3 split rear seat bench, which has larger manufacturing tolerances, to be removable with the at least extensive freedom of play desired when installed.

According to the invention, the tolerance compensation elements are described in more detail in two exemplary embodiments as follows, depending on the installation location of the tolerance compensation elements, which can also be used in combination.

The first embodiment to avoid any play remaining in the z direction after assembly in the respective receptacle of a removable 1/3 vehicle seat or a 2/3 part of a removable rear seat bench relative to the locking and unlocking device is described in the description part based on the associated 1A until 1D explained in more detail.

In a preferred embodiment of the invention, the tolerance compensation element of the first embodiment, which is integrated into the receptacle, is a cover in the manner of a cover element.

This cover element can be attached to the body-side receptacle and has elastically deformable damping tongues located lower than an upper edge of the receptacle in order to accommodate the seat feet in the vertical direction (z-direction) when installed.

In a preferred embodiment, the damping tongues each have at least one damping nub on their underside on the body side, whereby the damping tongues are supported on the body via the respective damping nub within the receptacle and thereby compensate for any play present in the vertical direction (z direction).

In a further preferred embodiment of the first embodiment, the damping tongues are connected to the cover element on both sides or on one side. Viewed in the direction of travel (x-direction), a front and rear seat foot is optionally arranged in formed damping tongues connected to the cover element on both sides and/or on one side of a one-piece cover element provided for the front and rear pair of seat feet.

For the front and rear seat feet of a pair of seat feet lying on one side, however, individual cover elements can also be arranged with the damping tongues just described that are connected to the cover element on one or both sides.

Finally, in a further embodiment it is also provided that the damping tongues connected to the cover element on both sides or one side have a rib or a pack of ribs, with the respective damping nub or several damping nubs then being arranged integrated in the rib pack arranged on the underside of the damping tongues .

The second embodiment of a removable 1/3 vehicle seat or a 2/3 part of a removable rear seat relative to the locking and unlocking device in order to avoid any play remaining in the z direction after assembly is described in the following part of the description based on the associated 2A until 2C explained in more detail.

The second embodiment is fundamentally characterized by the fact that the tolerance compensation element is arranged integrated in a seat base.

The tolerance compensation element is a support element that can be fastened in the seat base and which houses a damping block which is held on the support element via a cover element, the support element being arranged to be movable in a common locking step relative to the cover element in the vertical direction (z direction) in the installed state of the vehicle seat , whereby the carrier element is supported on the body via the respective damping block and the cover element. The damping block compensates for the play between the components caused by manufacturing tolerances in the assembled components after assembly in the vertical direction (z direction) via the carrier element that is movable relative to the cover element.

Further preferred embodiments of the invention result from the claims and from the following part of the description.

A first embodiment of a tolerance compensation element 20 with its configurations, in order to avoid any play in the z direction during assembly or installation, of a removable 1/3 seat 10, in particular a vehicle seat, in particular a rear seat, which is in a body-side receptacle 12 Body 40 is arranged, is first based on the associated 1A until 1D described. The solution presented below can be transferred to a larger and heavier 2/3 part of the rear seat bench.

1A shows a substructure of the body 40 of the rear seat. Particularly in the commercial vehicle sector but also in the passenger car sector, it is desirable to attach the second or third row of seats to the body 40 in such a way that the entire rear seat or parts of a multi-part rear seat can be easily removed.

The 1A shows the 1/3 part of such a back seat. This 1/3 part essentially corresponds to a single vehicle seat, on the basis of which the invention will be explained below.

In 1A 40 receptacles 12 are arranged below the vehicle seat on the body, these receptacles 12 sitting on the body 40 in the exemplary embodiment. Such recordings 12 can also be incorporated into the body 40 so that they do not build up on the surface of the body 40, but are arranged recessed in the body 40.

Front seat feet 14 are visible on the vehicle seat and are arranged in the receptacles 12 in the installed position of the vehicle seat. The recording 12 is an example only for the in 1A visible front right seat foot 14 shown.

Such a one-piece receptacle 12 runs on both sides of the vehicle seat, in the exemplary embodiment in the x direction, i.e. in the later direction of travel of the vehicle, and accommodates a front seat foot 14 and a rear seat foot 16, with the rear seat feet 16 in 1A are not visible. In the exemplary embodiment, the rear seat feet 16 are lower than the front seat feet 14 compared to an imaginary horizontal plane of the body 40. The receptacle 12 can also be designed in two parts on each side, so that ultimately each seat foot 14, 16 sits in its own separate receptacle 12.

In addition to the 1/3 part of the rear seat, the 2/3 part of the rear seat is indicated by its front seat feet 14.

1 B shows an enlarged side view of the vehicle seat from the in 1A visible side. In the 1 B The front seat foot 14 and the rear seat foot 16 can now be seen. Seen in the x direction, between the seat feet 14, 16 there is a locking and unlocking device 18 with a catch hook, which, when the vehicle seat is installed, surrounds a member arranged in the receptacle 12, in particular a retaining bolt attached to the receptacle 12, so that a 1/3 -Part of the rear seat or a 2/3 part of the rear seat can be locked and unlocked using a catch hook via the retaining bolt in the receptacle 12.

Due to the manufacturing tolerances of the body-side receptacle 12 and/or the locking and unlocking device 18 and/or the front and rear seat feet 14, 16, remaining play in the z direction cannot be ruled out after the vehicle seat has been locked between the assembly components.

To avoid this problem, a tolerance compensation element 20 is arranged between the seat feet 14, 16 and the body-side receptacle 12. This tolerance compensation element 20 is how 1A shows, placed on the recording 12, the essential elements of which are arranged within the receptacle 12, so that the tolerance compensation element 20 is ultimately arranged integrated in the receptacle 12.

As the 1C and 1D show in more detail, the tolerance compensation element 20 is a cover in the manner of a cover element, which is shown in a top view of the 1C and in a bottom view of the 1D is shown.

In the bottom view of the 1D It first becomes visible how the cover element is fastened in the receptacle 12. A receiving opening 29 is provided in the cover element, via which the cover element can be fastened via a receiving-side expansion member, which engages in the receiving opening 29 and then expands. On the rear side of the cover element, viewed in the x direction, fastening elements 28 are provided, which can be clipped into holding elements on the receiving side that correspond in terms of their shape.

The 1C and 1D show from above and below that lower-lying, elastically deformable damping tongues 21, 22 are arranged in the cover element compared to the upper edge of the receptacle 12. Since the rear seat feet 16 are lower when installed compared to the horizontal plane of the body 40, the rear damping tongue 22 is arranged lower in the cover element.

In the illustrated embodiment, the damping tongue 22, which accommodates the front seat feet 14, is designed so that it has connections 22A, 22B to the cover element on both sides within the cover element. The damping tongue 21 provided for the rear seat feet is only connected to the cover element on one side.

This design of the damping tongues 21, 22 can be varied depending on the existing and/or expected weight forces and/or crash forces introduced into the cover element via the vehicle seat.

The damping tongue 21, which has a one-sided connection 21A, has a greater spring effect than the damping tongue 22, which has a connection 22A, 22B on both sides. However, the damping tongue 22 is subject to a crash acting on the damping tongues 22 from the z-direction and x-direction with respect to the receptacle 12 -Forces are designed to be more stable overall, so that the damping tongues 21, 22 in the cover element can be designed, depending on the conditions with regard to an expected force input, during normal use and for an expected force input in a possible crash.

It is possible to use the damping tongue 21, which only has a one-sided connection 21A, for both the front and rear seat feet 14, 16.

It is also possible to use the damping tongue 22 with the connections 22A, 22B on both sides for the front and rear seat feet 14, 16.

After all, this can happen in the 1C and 1D Tolerance compensation element 20 shown can also be designed so that the damping tongue 21 accommodates the front seat feet 14 and the damping tongue 22 is designed in the rear area to accommodate the rear seat feet 16.

Depending on the design, the damping tongues 21, 22 have a predeterminable elasticity and can be elastically deformed when forces acting on them occur, analogous to spring elements, while building up a restoring force relative to the component causing the force input.

In order to ensure increased stability of the damping tongues 21, 22, individual ribs or rib packages 24 are arranged on the top and/or bottom. As a result, the damping tongues 21, 22 can be made thin on the material side.

Such ribs or such a rib package 24 is arranged on the underside of the damping tongues 21, 22 in the exemplary embodiment. In addition, damping knobs 23 are arranged on the underside of the damping tongues 21, 22 in the rib pack 24, by means of which the tolerance compensation element 20, designed as a cover element, rests on the body 40 in a damped manner.

If the vehicle seat is arranged in the receptacle 12, with the cover element arranged thereon as a tolerance compensation element 20, and locked via the locking and unlocking device 18, the front and rear seat feet 14, 16 are supported by the weight of the vehicle seat on the respective damping tongues 21, 22 via the damping knobs 23 on the body 40, the locking taking place with slight elastic deformation of the damping tongues 21, 22 and the damping knobs 23. The elastic restoring effect of the damping tongues 21, 22 and the damping knobs 23 - in the manner of a spring element - causes the vehicle seat to be firmly seated relative to the locking and unlocking device 18, which holds the vehicle seat in the z direction Press the device vertically upwards on the locking and unlocking device 18, which tries to lock the vehicle seat in the opposite direction via the catch hook of the locking and unlocking device 18. Any play that may be present is thus compensated for and rattling noises are avoided.

So that the locking and unlocking device 18 can grip the receiving-side bolt (not shown) with its catch hook, the cover element, as in the 1C and 1D becomes visible, a clearance 26 so that the bolt can reach through the cover element.

Below is the second embodiment with its configurations based on the associated 2A until 2C a removable 1/3 vehicle seat, which can also be transferred to the 2/3 part of a rear seat.

2A equals to 1A , however, is missing 2A the cover element, which rests on the receptacle 12, is arranged between the receptacle 12 and the seat feet 14, 16.

When the vehicle seat is installed, the seat feet 14, 16 of a pair of seat feet are placed directly into the respective receptacle 12.

How 2 B shows, tolerance compensation elements 30 are arranged on each of the seat feet 14, 16 of the vehicle seat to compensate for tolerances in the z direction, i.e. again to avoid play in the assembled components 12, 18.

The tolerance compensation element 30 of the second embodiment comprises a support element 32 which can be fastened in the seat feet 14, 16 and which can be locked into openings provided in the seat feet 14, 16 via locking elements 32B arranged on the support element 32.

The carrier element 32 houses a damping block 34, which is made of an elastic material, such as rubber, or the like, so that the elastically deformable damping block 34 builds up a restoring force against an acting force and thus also acts like a spring element.

The damping block 34 is held on the carrier element 32 via a cover element 36. For this purpose, the cover element 36 engages in a circumferential or locally formed latching step 32A of the carrier element 32. This locking step 32A is designed so that it allows movement of the cover element 36 relative to the carrier element 32 in the z direction. The cover element 36 itself is supported within the receptacle 12 on the body 40.

When the vehicle seat is installed, the weight of the vehicle seat or an additional crash force acting on the vehicle seat causes an elastic deformation of the damping block 34 seated in the carrier element 32 relative to the cover element 36 supported on the body 40. The carrier element 32 shifts in z direction downwards, since the damping block 34 is compressed by the weight force acting on the damping block 34 or an additional crash force of the vehicle seat. A gap 38 that compensates for the tolerances is provided between the carrier element 32 and the cover element 36, which is reduced in the z direction when the vehicle seat is installed.

The damping block 34 or the damping blocks 34 of the seat feet 14, 16 try to relax like a spring against the force acting from above through the vehicle seat. As a result, the damping blocks 34 push the support element 32 and thus the vehicle seat upwards in the z direction due to their restoring force.

Thus, each of the seat feet 14, 16 in the receptacle 12 is, on the one hand, supported downwards in the z-direction via the cover element 36 under slight prestress between the support element 32 and the cover element 36 relative to the body 40 and, on the other hand, the seat feet 14, 16 are supported via the support element 32 and with them the locking and unlocking device 18 of the vehicle seat is pushed upwards. This results in a gap width of the gap 38 depending on the material used for the damping blocks 34 and depending on the weight force or any crash forces that may occur between the carrier element 32 and the cover element 36. The catch hook of the locking and unlocking device 18 of the vehicle seat, which engages from below on the receiving-side bolt (not shown), in turn exerts a locking force on the vehicle seat, which presses the vehicle seat downwards into the receptacle 12 in the opposite direction to the restoring force of the damping blocks 34, which is caused by the manufacturing tolerances The play that may occur in the z direction in the assembly parts, which avoids opposing force effects and ensures a rattle-free, firm locking of the vehicle seat.
