Abstract

The invention relates to a spring, in particular to move at least one part of a fixture of the vehicle interior space. It was the object of the invention to create a spring, that does not cause disturbing noises due to vibrations. The object is solved by the spring being made of plastic.

First claim

The invention claimed is:

1. A fixture of a vehicle interior space comprising:
a first part;
a second part that can be moved in relation to the first part between a first position and a second position; and
a spring that urges the second part into the first position and that comprises
a first end ring;
a second end ring; and
a tubular wall extending along a longitudinal axis between the rings and formed of first plastic filaments extending at an angle to the longitudinal axis and second plastic filaments also extending at an angle to the axis, and crossing the first filaments, the end rings having a first spacing from each other in a slackened first position of the spring with the tubular wall radially constricted between the rings and a different second spacing shorter than the first spacing from each other in at least one loaded second position with the tubular wall radially bulging between the rings.

2. The fixture according to claim 1 , wherein the spring is a compression spring or a tension spring.

3. The fixture according to claim 1 , wherein the spring is extensible or compressible in a direction parallel to the longitudinal axis.

4. The fixture according to claim 1 , wherein the fixture is a headrest.
