Sleeve for a neck rest with tolerance compensation
View Patent ↗A sleeve for a neck rest with tolerance compensation, includes a sleeve body of plastic material for the accommodation of a rod of the neck rest. The sleeve body includes at least one integrally formed resilient portion which is biased toward or away from the interior of the sleeve body. A wire portion is attached to the sleeve body parallel to the axis of the sleeve body such that the wire portion can be resiliently deflected away from or towards the sleeve body, the wire portion engaging the resilient portion.
1. A sleeve for a neck rest with tolerance compensation, said sleeve comprising:
a sleeve body defining a hollow interior for accommodating a rod of the neck rest, the sleeve body including at least one integrally formed resilient portion which is biased in a first direction; and
a wire portion attached to the sleeve body along an axial direction of the sleeve body such that the wire portion is resiliently deflected in a second direction different from the first direction, the wire portion engaging the resilient portion;
wherein the wire portion is parallel to the axial direction of the sleeve body.
2. The sleeve of claim 1 , wherein the first and second directions are opposite radial directions of the sleeve body.
3. The sleeve of claim 1 , wherein the sleeve body is of plastic material.
4. The sleeve of claim 1 , wherein the wire portion is of resilient metal.
5. The sleeve of claim 1 , wherein
the resilient portion is biased outwardly away from the interior of the sleeve body; and
the wire portion is resiliently deflected towards the interior of the sleeve body, the wire portion engaging an inner side of the resilient portion.
6. The sleeve of claim 5 , comprising
two said resilient portions which are spaced from each other in the axial direction of the sleeve body; and
a single said wire portion which is attached to the sleeve body and has opposite end portions which engage the resilient portions, respectively.
7. The sleeve of claim 5 , wherein the wire portion is fixedly clamped to the outer side of the sleeve body through at least a retaining portion integrally formed with the sleeve body.
8. The sleeve of claim 7 , wherein
the retaining portion includes at least one hook portion extending transverse to the axial direction of the sleeve body and being formed on an outer surface of the sleeve body; and
the wire portion is laterally clipped between the hook portion and the outer surface of the sleeve body, with a free end of the hook portion at least partially gripping over the wire portion.
9. A sleeve for a neck rest with tolerance compensation, said sleeve comprising:
a sleeve body defining a hollow interior for accommodating a rod of the neck rest, the sleeve body including at least one integrally formed resilient portion which is biased in a first direction; and
a wire portion attached to the sleeve body along an axial direction of the sleeve body such that the wire portion is resiliently deflected in a second direction different from the first direction, the wire portion engaging the resilient portion;
wherein the resilient portion is biased towards the interior of the sleeve body; and
wherein the wire portion is attached to an outer side of the sleeve body to be resiliently deflected away from the sleeve body, the wire portion engaging an outer side of the resilient portion.
10. The sleeve of claim 9 , comprising two said resilient portions which are spaced from each other in the axial direction of the sleeve body; and
a single said wire portion which is attached to the sleeve body and has opposite end portions which engage the resilient portions, respectively.
11. The sleeve of claim 9 , wherein the wire portion is fixedly clamped to the outer side of the sleeve body through at least a retaining portion integrally formed with the sleeve body.
12. The sleeve of claim 11 , wherein
the retaining portion includes at least one hook portion extending transverse to the axial direction of the sleeve body and being formed on an outer surface of the sleeve body; and
the wire portion is laterally clipped between the hook portion and the outer surface of the sleeve body, with a free end of the hook portion at least partially gripping over the wire portion.
