Abstract

A seat actuating element for a motor vehicle seat has an element head ( 9 ) and a guide rod ( 10 ) that is received movably in a seat wall ( 7 ) of the motor vehicle seat ( 1 ). The element head ( 9 ) is arranged on the seat wall ( 7 ) and can be actuated. The seat actuating element ( 6 ) has an adjustment protector ( 11 ) to avoid inadvertent actuation of the seat actuating element ( 6 ).

First claim

What is claimed is:

1. A seat actuating element for adjusting a position of a motor vehicle seat, the seat actuating element mounted on a seat wall of the motor vehicle seat and comprising:
a guide rod received movably in an opening in the seat wall, the guide rod having an axis arranged substantially normal to the seat wall, the guide rod being movable in at least one direction normal to the axis of the guide rod to adjust the position of the motor vehicle seat;
an element head mounted on the guide rod, the element head having a facing surface spaced from and facing the seat wall, and a pressing surface opposite the facing surface, at least one indentation provided in the facing surface of the seat actuating element and extending towards the pressing surface, the at least one indentation having a cross-section that narrows from the facing surface towards the pressing surface; and
at least one protrusion projecting from the seat wall at a position facing the at least one indentation and configured to be inserted into the at least one indentation, wherein
the at least one protrusion is received in the at least one indentation to prevent movement of the guide rod normal to the axis of the guide rod to form a non-positive connection to prevent inadvertent actuation of the seat actuating element.

2. The seat actuating element of claim 1 , wherein the guide rod ( 10 ) has a blocking element ( 17 ) of the adjustment protector ( 11 ), the blocking element ( 17 ) being of complementary configuration with respect to a receiving opening ( 20 ) of the seat wall ( 7 ), the receiving opening ( 20 ) receiving the guide rod ( 10 ) movably.

3. The seat actuating element of claim 2 , wherein the blocking element ( 17 ) tapers toward an end ( 19 ) of the guide rod ( 10 ) that faces away from the element head ( 9 ).

4. The seat actuating element of claim 1 , wherein the guide rod ( 10 ) is of telescopic configuration.

5. The seat actuating element of claim 1 , wherein the adjustment protection means ( 17 ) has a first blocking element part ( 22 ) on a first blocking element face ( 25 ) and a second blocking element part ( 23 ) and a second blocking element face ( 25 ) that is opposed to the first blocking element face ( 25 ), the first and second blocking element parts ( 22 , 23 ) being configured in a complementary and positively locking manner, and the first blocking element part ( 22 ) or the second blocking element part ( 23 ) being fixed on the guide rod ( 10 ).

6. The seat actuating element of claim 1 , wherein a face ( 14 ) of the element head ( 9 ) that faces the seat wall ( 7 ) has a friction lining ( 29 ).

7. The seat actuating element of claim 1 , wherein the adjustment protector ( 11 ) has a blocking element ( 17 ) that spans the element head ( 9 ) in its axial extent while maintaining a further spacing (B).

8. The seat actuating element of claim 1 , wherein the motor vehicle seat is electrically adjustable.
