Abstract
A plastic headrest sleeve receiving a headrest rod and comprising a tube fitted at its top end with a flange within which a slider is displaceably supported between a locked position, wherein it locks the headrest rod, and a release position, the wall of the said tube being fitted between its ends with at least one resilient clamping segment, a spring being mounted on the tube outside and biasing the resilient segment toward the tube inside, and a drive element displaceably resting on the tube, said drive element being operationally connected to the slider and the clamping segment in a manner that the spring's action on the clamping segment shall be reduced or eliminated when the slider is displaced into the release position.
Claims9
A plastic headrest sleeve for receiving a headrest rod, said headrest sleeve comprising:
- a tube having top and bottom ends, wherein a wall of the tube comprises at least one resilient clamping segment between the top and bottom ends;
- a flange at the top end of the tube;
- a slider that is supported by the flange and displaceable between a position locking the headrest rod and a release position,
- a drive element;
- and
- a helical spring that is mounted on an outside of the tube and automatically biases the resilient clamping segment into an inside of the tube, one end of the helical spring being connected to the drive element and the other end of the helical spring being affixed to the tube;
- wherein the drive element is displaceably supported on the tube and is operationally connected to the slider and the resilient clamping segment in such a manner that spring action of the helical spring on the resilient clamping segment is reduced or eliminated when the slider is displaced into the release position.
A plastic headrest sleeve for receiving a headrest rod, said headrest sleeve comprising:
- a tube having top and bottom ends, wherein a wall of the tube comprises at least one resilient clamping segment between the top and bottom ends, and wherein the resilient clamping segment is constituted by a section of the wall between two mutually spaced-apart, parallel slots in the wall of the tube;
- a flange at the top end of the tube;
- a slider supported by the flange and displaceable between a position locking the headrest rod and a release position;
- a drive element;
- and
- a spring mounted on an outside of the tube and biasing the resilient clamping segment into an inside of the tube;
- wherein the drive element is displaceably supported on the tube and is operationally connected to the slider and the resilient clamping segment in such a manner that spring action of the spring on the resilient clamping segment is reduced or eliminated when the slider is displaced into the release position.
A plastic headrest sleeve for receiving a headrest rod, said headrest sleeve comprising:

- a flange at the top end of the tube;
- a slider supported by the flange and displaceable between a position locking the headrest rod and a release position;
- a drive element;
- and
- a spring mounted on an outside of the tube and biasing the resilient clamping segment into an inside of the tube;
- wherein
- the resilient clamping segment comprises, on the inside of the tube, a boss for engaging the headrest rod;
- and
- the drive element is displaceably supported on the tube and is operationally connected to the slider and the resilient clamping segment in such a manner that spring action of the spring on the resilient clamping segment is reduced or eliminated when the slider is displaced into the release position.
