ADJUSTING DEVICE FOR ADJUSTING A MOTOR VEHICLE SEAT, MOTOR VEHICLE SEAT, MOTOR VEHICLE AND METHOD FOR ADJUSTING A MOTOR VEHICLE SEAT
An adjusting device for adjusting a motor vehicle seat is provided. The adjusting device includes a locking device with a step-up transmission unit, a pulling force element configured for actuation and coupled to the step-up transmission unit and a resetting device configured to reset the step-up transmission unit into a starting state. The resetting device is at least partially integrated in the pulling force element. A motor vehicle seat, a motor vehicle, and a method for adjusting a motor vehicle seat using the adjusting device are also provided.
1 . An adjusting device for adjusting a motor vehicle seat, the adjusting device comprising:
a locking device comprises a step-up transmission device;
a pulling force element configured for actuation and coupled to the step-up transmission device;
a resetting device configured to reset the step-up transmission device into a starting state, wherein the resetting device is at least partially integrated in the pulling force element.
2 . The adjusting device according to claim 1 , wherein the adjusting device is a discontinuous adjusting device for adjusting a backrest position of the motor vehicle seat.
3 . The adjusting device according to claim 1 , wherein the pulling force element at least partially comprises an elastic portion that is elastic in a pulling direction.
4 . The adjusting device according to claim 3 , wherein the elastic portion is formed from an elastic material.
5 . The adjusting device according to claim 4 , wherein the elastic portion is formed from spring steel.
6 . The adjusting device according to claim 1 , wherein the resetting device comprises a deflection part in a connecting region of the pulling force element with the step-up transmission device, along which the pulling force element runs at least partially.
7 . The adjusting device according to claim 1 , wherein the step-up transmission device is a rotary lever configured to be rotated about a rotation axis.
8 . The adjusting device according to claim 7 , wherein the rotary lever is seated with play on the rotation axis in a play-affected manner.
9 . The adjusting device according to claim 8 , wherein the play of the rotary lever is dimensioned such that this corresponds to a tautening distance of the pulling force element, so that the pulling force element is brought from an untautened into a tautened state during movement within the play.
10 . The adjusting device according to claim 7 , wherein on the rotary lever of the step-up transmission device, two pulling force elements acting in different directions of rotation are arranged.
11 . The adjusting device according to claim 1 , further comprising an operating unit that is arranged spaced from the step-up transmission device.
12 . The adjusting device according to claim 11 , wherein the operating unit is a rotary lever configured to be rotated about a rotation axis.
13 . The adjusting device according to claim 1 , wherein a connecting point of the pulling force element with the step-up transmission device is spaced from a rotation axis at an end of a deflection device, so that a torque results on a contact point of the pulling force element and the deflection device.
14 . A motor vehicle seat having an adjusting device comprising:
a locking device comprising a step-up transmission unit;
a pulling force element configured for actuation and coupled to the step-up transmission unit; and
a resetting device configured to reset the step-up transmission unit into a starting state, wherein the resetting device is at least partially integrated in the pulling force element.
15 . The motor vehicle seat according to claim 14 , wherein the motor vehicle seat has a backrest that can be adjusted relative to a seat part.
16 . A motor vehicle having a seat unit for a vehicle occupant, wherein the seat unit is configured as motor vehicle seat with an adjusting device comprising:
a locking device comprising a step-up transmission unit;
a pulling force element configured for actuation and coupled to the step-up transmission unit; and
a resetting device configured to reset the step-up transmission unit into a starting state, wherein the resetting device is at least partially integrated in the pulling force element.
17 . The motor vehicle according to claim 16 , wherein the motor vehicle is a passenger motor vehicle.
18 . A method for adjusting a motor vehicle seat by means of an adjusting device having at least two locking devices, the method comprising the steps of:
moving an operating unit of the adjusting device;
during the moving, overcoming a play in a pulling force element coupled to the operating unit; and
tautening the pulling force element.
19 . The method according to claim 18 , wherein the adjusting device is a discontinuous adjusting device and the method results in the adjusting of a backrest position of the motor vehicle seat.
