Abstract

A system includes a pivotable armrest ( 1 ) and a pendulum element ( 18 ). The armrest ( 1 ) is pivotably hinged on a holding device ( 10 ) around a primary axis ( 11 ). The armrest ( 1 ) is connected rotatably fixed to a connection element ( 15 ). The holding device ( 10 ) includes the pendulum element ( 18 ). The pendulum element ( 18 ) is pivotable around a secondary axis ( 12 ). The connection element ( 15 ) and the pendulum element ( 18 ) are configured such that the pendulum element ( 18 ) is pivoted into a first position when a force is exerted on the system. The pendulum element ( 18 ) pivoted in the first position interlockingly interacts with the connection element ( 15 ) in such a way that a pivoting of the connection element along a second direction of rotation ( 32 ) is countered. The first direction of rotation ( 31 ) runs counter to the second direction of rotation ( 32 ).

First claim

1 . A system comprising:
a pivotable armrest; a bracket device comprising a bracket, a pendulum element and a connecting element, wherein the armrest is articulated on the bracket device so as to be pivotable about a primary axis, wherein the armrest is connected rotationally conjointly to the connecting element, wherein the pendulum element is pivotable about a secondary axis, wherein the connecting element and the pendulum element are configured such that, when a force acts on the system, the pendulum element can be pivoted into a first position, wherein the pivoted pendulum element, in the first position, interacts positively lockingly with the connecting element such that the positive locking counteracts a pivoting of the connecting element along a second direction of rotation, wherein a first direction of rotation runs oppositely to the second direction of rotation.

2 . The system as claimed in claim 1 , wherein the pendulum element is preloaded with a restoring force by way of a spring element, wherein the spring element is configured such that the restoring force counteracts a pivoting movement of the pendulum element along the first direction of rotation.

3 . The system as claimed in claim 2 , wherein the spring element articulated on the bracket device.

4 . The system as claimed in claim 2 , wherein the spring element is configured such that the force acting on the system must exceed a threshold value for the pivoting of the pendulum element.

5 . The system as claimed in claim 1 , wherein the bracket device has a second abutment, wherein the second abutment is configured such that, during a pivoting of the pendulum element along the first direction of rotation, the positioning of the pendulum element for the positively locking interaction with the connecting element can be assisted by way of the second abutment.

6 . The system as claimed in claim 1 , wherein the pendulum element and the connecting element are configured such that the positively locking interaction between pendulum element and connecting element takes place along a direction running substantially perpendicular to the force direction.

7 . The system as claimed in claim 1 , wherein the pendulum element comprises a first contact surface and the connecting element comprises a second contact surface, wherein the first contact surface and the second contact surface are arranged in contact with one another during the positively locking interaction of the pendulum element with the connecting element.

8 . The system as claimed in claim 1 , wherein the pivotable armrest can be transferred reversibly between a usage position and a stowage position, wherein the system is configured such that the positively locking interaction prevents the armrest from departing from the stowage position, wherein the armrest runs substantially horizontally in the usage position and runs substantially vertically in the stowage position.

9 . The system as claimed in claim 1 , wherein the connecting element has a stop element, wherein, in the usage position, the stop element interacts with a first abutment of the device in positively locking fashion along the second direction of rotation.

10 . A backrest for a motor vehicle seat, wherein the backrest comprises a system having a pivotable armrest and having a pendulum element.

11 . A motor vehicle seat which has a system having a pivotable armrest and having a pendulum element.
