Abstract

In a brake assembly for an air vent in a vehicle, comprising two brake components which are movable relative to each other, wherein on at least one brake component a friction lining is provided, which rubbingly rests against the respective other brake component and inhibits a mutual movement of the brake components, it is provided that the friction lining is made of a thermoplastic elastomer which contains a silicone admixture. A friction lining for such brake assembly is made of a thermoplastic elastomer which contains a silicone admixture.

First claim

The invention claimed is:

1. A brake assembly for an air vent in a vehicle, comprising two brake components which are movable relative to each other, wherein on at least one brake component a friction lining is provided which rubbingly rests against the respective other brake component and inhibits a mutual movement of the brake components, wherein the friction lining has a partly spherical friction surface and the respective other brake component has a partly spherical contact surface for the friction lining, wherein the at least one brake component includes a cutout, wherein a first portion of the friction lining is securely retained by the at least one brake component within the cutout, and wherein a second portion of the friction lining protrudes beyond an outer surface of the at least one brake component, and wherein the friction lining is made of a thermoplastic elastomer which contains a silicone admixture.

2. The brake assembly of claim 1 wherein the silicone admixture is in a range from 0.5% to 5%.

3. The brake assembly claim 1 wherein the friction lining is positively and/or cohesively connected with the at least one brake component.

4. The brake assembly claim 1 wherein the friction lining is arranged on a carrier which is urged against the respective other brake component by spring action.

5. The brake assembly claim 1 wherein the first or the second brake component is coupled with one of a diverter, an operating element or a closing flap.

6. The brake assembly of claim 5 wherein the diverter, the operating element or the closing flap can be pivoted, rotated and/or shifted.

7. A brake assembly for an air vent within a vehicle, the brake assembly comprising:
a first brake component including a semi-spherical bearing shell;
a semi-spherical second brake component that couples to the bearing shell, wherein the second brake component includes a cutout, wherein the second brake component is urged against the bearing shell via spring force; and
a friction lining carried on the second brake component, wherein the friction lining has a semi-spherical friction surface that rests against the bearing shell and inhibits mutual rotation or pivoting of the first and second brake components, wherein a first portion of the friction lining is securely retained by the second brake component within the cutout, wherein a second portion of the friction lining protrudes beyond an outer surface of the second brake component, and wherein the friction lining is formed of a thermoplastic elastomer that contains a silicone admixture.

8. The brake assembly of claim 7 , wherein the silicone admixture is in a range from 0.5% to 5%.

9. The brake assembly claim 7 , wherein the friction lining is positively and/or cohesively connected with the second brake component.

10. The brake assembly claim 7 , wherein the friction lining is arranged on a carrier which is urged against the first brake component by spring action.

11. The brake assembly of claim 10 , wherein the diverter, the operating element or the closing flap can be pivoted, rotated and/or shifted.

12. The brake assembly claim 7 , wherein the first or the second brake component is coupled with one of a diverter, an operating element or a closing flap.
