Armrest device
Armrest device, in particular for commercial vehicle seats, having a guide rail system for guiding a displacement movement of a first rail relative to a second rail which can be connected to the armrest device, in a displacement direction, wherein the displacement movement of the first rail can be arrested by the engagement of a locking element of a locking device in at least one recess in the first rail, wherein the locking device is rigidly connected to the armrest device by a first end and can be deflected in a height direction by a second end, the locking element engaging in the recess in a non-deflected position of the locking device.
1. An armrest system for a commercial vehicle, comprising:
a first rail selectively displaceable with respect to a second rail in a longitudinal direction of the first and second rails, wherein the first rail has a plurality of apertures and the second rail has an aperture;
an arm rest connected to an upper surface of the first rail;
a locking device having a first end connected to a lower surface of the second rail, the locking device having a second end opposing the first end, and the locking device having a locking element that is aligned with the aperture of the second rail, wherein at least a portion of the locking device is elastically deformable;
wherein in a locked state, the locking element extends through the aperture of the second rail and one of the apertures of the first rail to lock the relative positions of the first and second rails in the longitudinal direction; and
wherein in an unlocked state, at least a portion of the locking device elastically deforms and the second end of the locking device deflects by a predetermined distance from the lower surface of the second rail, and the locking element is positioned below the plurality of apertures of the first rail such that the first rail is displaceable with respect to the second rail in the longitudinal direction of the first and second rails.
2. The armrest system of claim 1 , further comprising:
a cable connected to the second end of the locking device and oriented substantially perpendicular to the first and second rails, wherein a force applied to the cable elastically deforms at least a part of the locking device and deflects the second end of the locking device by the predetermined distance from the lower surface of the second rail.
3. The armrest system of claim 1 , wherein the locking element is positioned at a midpoint of the locking device between the first and second ends of the locking device.
4. The armrest system of claim 1 , wherein the locking element is positioned on a support of the locking device, and a first steel spring sheet extends from the support to the first end of the locking device, and a second steel spring sheet extends from the support to the second end of the locking device, wherein the first and second steel spring sheets are elastically deformable.
5. The armrest system of claim 1 , wherein the locking device is larger than the second rail in the longitudinal direction such that the locking device is configured to be manually deflectable into the unlocked state.
6. The armrest system of claim 1 , further comprising:
an armrest support positioned between the second rail and the locking element, the armrest support having an aperture that is aligned with the aperture of the second rail, and the first end of the locking element is connected to the armrest support.
