Embodiment Construction

[0030] figure 1 A diagram schematically represents the force-travel curve of the adjusting device 100 . This force-travel curve characterizes the torque at which the snap-fit ​​fitting unit operates. This is measured in the assembled state, ie on the seat to be adjusted. For better comparison in case A, the force-travel curve according to the prior art is therefore drawn in dashed lines. On the abscissa, the graph represents the path that is applied for the adjustment in the operating situation of the adjusting device 100 , here in the form of an angle of rotation in degrees. On the ordinate, the force to be exerted over the travel is plotted here as torque with the unit Nm. The abscissa is divided in 5° increments. The vertical axis is divided into 1Nm scales. To adjust the backrest, the adjusting device is actuated via a force transmission mechanism, here in the form of a lever mounted rotatably about an axis of rotation. Up to a swivel angle of approximately 6-7°, the...

Abstract

An adjusting device for adjusting a motor vehicle seat is provided. The adjusting device includes an engagement fitting unit, a force transmission device configured to transmit a force for locking and unlocking the engagement fitting unit, and a force step-up transmission device configured to step up the force transmitted by the force transmission device. A motor vehicle seat, a motor vehicle, and a method for adjusting a motor vehicle seat using the adjusting device are also provided.

Description

technical field [0001] The invention relates to an adjusting device for adjusting a car seat. [0002] The invention also relates to a car seat. [0003] The invention also relates to an automobile, [0004] Furthermore, the invention relates to a method for adjusting a motor vehicle seat by means of an adjusting device. Background technique [0005] Motor vehicles with seats are known from the prior art, in which the position of the backrest, in particular relative to the seat part, is adjustable. This adjustment takes place via a joystick mechanism mounted on the seat or another operating mechanism fixed there. In this case stepless and discontinuous adjustment by means of actuators, ie stepwise adjustment with known mechanical solutions. In the case of a mechanical adjustment, the locking device or locking device of the adjusting device can be unlocked for adjustment and locked for locking in order to perform the adjustment. This is done via the actuating lever by tr...
