Abstract

Adjustable height limiter for a vehicle seat, comprising: a main body with a slot having a first end and a second end, a piston rod element which is displaceable with respect to the main body and has a pin element which is guided in the slot, a sleeve element which is rotatable with respect to the main body and at least partially surrounds the main body, the sleeve element having a boundary which is helical with respect to the main body, the boundary being arranged between the first end and the second end when viewed in the extension direction of the slot, and the pin element being arranged between the first end and the boundary.

First claim

What is claimed is:

1. An adjustable height limiter for a vehicle seat, comprising:
a main body having a slot which has a first end and a second end;
a piston rod element which is displaceable with respect to the main body having a pin element which is guided in the slot, wherein the pin element is fixed to the piston rod element; and
a first sleeve element which is rotatable with respect to the main body and at least partially surrounds the main body, the first sleeve element having a first boundary which is helical with respect to the main body, the first boundary being arranged between the first end and the second end when viewed in the extension direction of the slot, and the pin element being arranged between the first end and the first boundary, wherein a movement of the piston rod element in a first direction is limited by the first boundary.

2. The adjustable height limiter according to claim 1 , wherein the pin element extends through the slot.

3. The adjustable height limiter according to claim 1 , wherein a first end of a first Bowden cable is connected to the first sleeve element, the first sleeve element being rotatable by actuation of the first Bowden cable.

4. The adjustable height limiter according to claim 3 , wherein a first spring element is provided comprising a first spring end and a second spring end, the first spring end being connected to the main body and the second spring end to the first sleeve element.

5. The adjustable height limiter according to claim 1 , wherein the first boundary is wave-shaped.

6. The adjustable height limiter according to claim 1 , wherein the first boundary has a first planar section and a second planar section.

7. The adjustable height limiter according to claim 1 , wherein a first fastening eye is arranged on the main body and a second fastening eye is arranged on the piston rod element, the first fastening eye and the second fastening eye each having an elastic element.

8. The adjustable height limiter according to claim 7 , wherein the elastic element is made of a polyurethane elastomer.

9. The adjustable height limiter according to claim 3 , wherein a first guide element is provided which is rigidly connected to the main body and is provided to guide the first Bowden cable.

10. An adjustable height limiter for a vehicle seat, comprising:
a main body with a first cover element and a slot extending from a first end to a second end;
a piston rod element displaceable with respect to the main body and comprising a pin element affixed to the piston rod element, the pin element moveable along a length of the slot by the piston rod element;
a rotatably mounted base element displaceably arranged with respect to the main body and at least partially within the main body, the rotatably mounted base element comprising a helical first boundary positioned between the first end and the second end; and
the first cover element having formed a first step when viewed in the transverse direction and the base element having formed a second step when viewed in the transverse direction, it being possible to bring the first step and the second step into contact.

11. A vehicle seat having an adjustable height limiter according to claim 1 .
