Abstract

The height adjuster (1) is for a seat with a frame (2) having adjuster wheels (3) mounted on it. The wheels rotate around axes (3a) orthogonal to the longitudinal plane of the adjuster. The wheels mesh with racks (2a) which move on the frame for height adjustment.

Description

The invention relates to a seat depth adjustment device for a motor vehicle seat according to the preamble of Pa claim 1.

With adjustment devices of this type (DE 196 12 853 A1) it is known to a seat depth adjustment Bearing shaft that carries gears at both ends with parallel to the longitudinal guide rails of the seat depths adjusting device arranged, rack-like counter pieces comb. The gear connection serves the Ver edges of the seat depth adjustment device in the relative to avoid short longitudinal guides. The well-known adjustment device has a considerable height, which the Un provision in a seat part of a vehicle seat sword.

The invention is based on this prior art the task of a seat depth adjustment the known type so that they are simple and is space-saving and is particularly flat.  

This problem is solved with the characteristics of Pa claim 1.

The arrangement of the wheels on the seat depth adjustment device tion causes a flat design with the result that the Seat depth adjustment device well in a vehicle seat can be brought and does not reduce the seating comfort. The construction is equally good for manual as for mo toric operation suitable and allows a simple Ar adjustment of the seat depth adjustment device.

Preferred embodiments of the invention result from the subclaims.

Two preferred embodiments of the Invention described with reference to the drawings. Show it:

Fig. 1 - a perspective view of the Sitztie fenverstellvorrichtung with manual actuation;

Fig. 2 - a perspective view of the Sitztie fenverstellvorrichtung with motorized actuation.

The seat depth adjustment device 1, called depth adjusting section below with the seat, has a carrier element 1 b, which is provided with guide rails 1 b a 2 in guide grooves longitudinally displaceably guided on the seat frame. 2 Parallel to the guide grooves 2 b are provided on the seat frame 2 against each other opposite, designed as racks counterparts 2 a, hereinafter referred to as counter areas, in which engage as wheels 3 designed as spur gears. The wheels 3 are on perpendicular to the guide plane of the Trägerele element 1 b extending axes of rotation 3 a on the carrier element 1 b ge. With the outer wheels 3 mesh intermediate wheels 4 , which are in engagement with each other and rotate about the axes of rotation 3 a parallel axes of rotation 4 a. About these inter mediate wheels 4 , the two outer wheels 3 are coupled slip-free.

In one of the wheels 4 , a locking piece 5 a, hereinafter referred to as the locking area, engages, which is arranged on a handle 5 , hereinafter referred to as the handle area. The locking area 5 a is designed as a toothed segment when the wheel 4 is a toothed wheel. The grip area 5 is fastened to the carrier element 1 b and can be pivoted about an axis 5 d. Designed as a lever handle portion 5 transmits a return spring 5 b, c located on a thrust bearing 5 at Slower lement bears 1 b. The return spring 5 b holds the Rastbe rich 5 a with the intermediate wheel 4 in engagement and thereby prevents the displacement of the seat depth adjustment area 1 relative to the seat frame 2 as long as the grip area 5 is not pivoted out.

After the locking area 5 a has been lifted by pivoting the Griffbe range 5 from the intermediate wheel 4 , the seat depth adjustment area 1 can be moved. If the seat depth adjustment area 1 is pushed ver in the direction of arrow 6 , the wheels 3 roll on the opposite areas 2 a in opposite directions with the directions of rotation 3 b and 3 c. The intermeshing with them and each other intermediate wheels 4 , which must inevitably in the directions of rotation 4 b and 4 c hen, cause that the outer wheels 3 can only rotate by the same angular amounts. This prevents the guide rails 1 a from tilting in the guide grooves 2 b.

In the motorized adjustment of the seat depth adjustment region 1 shown in FIG. 2, the wheels 3 and the intermediate wheels 4 are arranged identically to the previous embodiment according to FIG. 1. A gear wheel 5 e, which is designed as a worm wheel and engages rotatably on the grip area 5 ′, engages in one of the intermediate wheels 4 . The Ge gear wheel 5 e is driven by a flexible shaft 5 f by a drive motor, not shown, which can be arranged at a remote location from the seat depth adjustment area 1 of the vehicle seat. The gear wheel 5 e is held by a return spring 5 b with the intermediate wheel 4 , which is provided on the 5 d pivotable about the axis Griffbe rich 5 '.

The spring-actuated gear connection prevents an overload of the mechanics of the seat depth adjustment area 1 in the event of obstacles in the displacement path. The adjustment of the seat depth adjustment area 1 is also possible by hand in an emergency. The except for the grip area 5 ; 5 'identical design of the motor-adjustable seat depth adjustment area with the manually adjustable, also reduces the cost of manufacture.
