Armrest device for a vehicle interior

摘要

Armrest device having an armrest part swivellably movable between an armrest position and a not-in-use position, having a base part arranged fixed in the vehicle and on which the armrest part is mounted swivellably movable about a swivel axis, and having a locking device for supporting the armrest part in at least one swivel position relative to the base part. The swivel axis is axially split into a base axis section and an armrest axis section, and the locking device includes a wrap spring brake which interacts with the base axis section and the armrest axis section in order to release the armrest part during a swivel movement in the direction of the not-in-use position and to lock it during a reverse swivel movement.

1. An armrest device for a vehicle interior comprising an armrest part movable between an armrest use position and a not-in-use position, a base part arranged fixed in the vehicle and on which the armrest part is mounted movable about a swivel axis, and a locking device for supporting the armrest part in at least one swivel position relative to the base part, wherein the swivel axis is axially split into a base axis section which is arranged stationary relative to the base part and into an armrest axis section which is arranged co-rotatable relative to the armrest part, wherein the locking device comprises a wrap spring brake which interacts with the base axis section and the armrest axis section such that the armrest part is released during a swivel movement in a direction of the not-in-use position and locked during a reverse swivel movement in a direction of the armrest use position, wherein the wrap spring brake comprises a helical wrap spring having windings coaxially surrounding the armrest axis section and the base axis section, where the windings surrounding the base axis section are wrapped around the base axis section in a rotation direction which causes an opening of the windings during a swivel movement of the armrest part in the direction of the not-in-use position.
