Problems solved by technology

On the other hand, an overly rigid connection has the disadvantage that, for example, in a rear-end collision, the impact force is introduced into the seat occupant in a rigid manner and causes him to be injured by a sudden return movement, such as a whiplash injury (Schleudertrauma )

Embodiment Construction

[0066] figure 1 An adjustment device in the form of a seat longitudinal adjustment device for a vehicle seat is shown in an overview. The adjusting device has an upper rail 3 connected to the vehicle seat and a lower rail 4 connected to the vehicle floor, the upper rail 3 and the lower rail 4 being displaceable relative to each other along a longitudinal direction X corresponding to the longitudinal direction of the vehicle.

[0067] The adjustment device is embodied as a spindle drive with an adjustment drive 2 arranged on the upper guide rail 3 , which is connected to the fixed position and is arranged on the lower guide rail 4 via a holder 6 in a rotationally fixed manner. The screw rod 1 remains engaged.

[0068] as by figure 2 with Figure 4 It can be seen that the transposition drive mechanism, for example according to the type disclosed by DE 103 37 475 A1 and DE 10 2006 049 809 A1, has a spindle nut 22 whose internal engagement in the form of an internal thread eng...

Abstract

An adjusting means for adjusting two vehicle parts relative to each other, in particular for the longitudinal setting of a vehicle seat is provided. The adjusting means comprising an adjusting gear unit (2) arranged on a first vehicle part and a spindle (1) arranged on a second vehicle part, which extends in longitudinal direction (X), is in engagement with the adjusting gear unit and along which the adjusting gear unit is movable for adjusting the first vehicle part relative to the second vehicle part. There is provided a reinforcement part (24, 24', 24'', 24''', 24*, 24**, 28, 28') which supports the adjusting gear unit with respect to the first vehicle part in the longitudinal direction of the spindle such that due to the reinforcement part with forces (F) introduced in the longitudinal direction from the first vehicle part into the adjusting gear unit the adjusting gear unit is supported with respect to the first vehicle part with a higher rigidity than with forces introduced against the longitudinal direction.

Description

[0001] This application is a divisional application of an invention patent application entitled "Screw Drive Mechanism with Reinforcement" with the application date of February 11, 2011 and the national application number of 201180009358.5 (PCT application number of PCT / EP2011 / 052027). . technical field [0002] The invention relates to an adjusting device for adjusting two vehicle components relative to one another, in particular for longitudinally adjusting a vehicle seat. Background technique [0003] Such an adjusting device configured as a spindle drive has an adjusting drive arranged on a first vehicle part and a spindle extending in the longitudinal direction which is arranged on a second vehicle part. Thus, the transposition transmission mechanism and the screw rod realize a screw transmission mechanism, the way is: the screw rod is engaged with the transposition transmission mechanism, and the transposition transmission mechanism moves along the screw rod for relati...
