Abstract

A glass run channel having a shock absorption member provided in a direction crossing a movement direction of a windowpane with a gap provided between a base bottom portion and the shock absorption member. A low-friction material layer is integrally provided at a contact face of the shock absorption member which is configured to come into contact with an edge of the windowpane and a back face of the contact face and/or a bottom face of the base bottom portion opposite the back face.

Claims

1. A glass run channel assembly for a window frame of a vehicle and adapted to slidably receive a windowpane, the glass run channel assembly comprising:

a main body portion including a pair of side wall portions and a base bottom portion connecting the pair of side wall portions;

seal lips protruding from an opening edge side of the pair of side wall portions to the base bottom portion,

a shock absorption member adapted to be provided in a direction crossing a movement direction of the windowpane with a gap provided between the base bottom portion and the shock absorption member; and

low-frictional material layers provided integrally at a contact face of the shock absorption member that is adapted to come into contact with an edge of the windowpane and at least one of a back face of the contact face and a bottom face of the base bottom portion opposite the back face;

wherein said low-friction material layer are composed of a thermoplastic elastomer; and

wherein the window pane is displaced towards the outside of the vehicle when the windowpane contacts the shock absorption member.

2. A glass run channel according to claim 1, wherein the shock absorption member is connected integrally with at least one of the base bottom portion and side wall portion at least partly of a widthwise direction.

3. A glass run channel according to claim 1, wherein the shock absorption member has a connecting portion integrally connected with at least one of the base bottom portion and the side wall portion, and is constructed so as to be protruded from the connecting portion in a cantilever beam shape.

4. A glass run channel according to claim 1, wherein the shock absorption member has connecting portions integrally connected with at least one of the base bottom portion and the side wall portion, and is constructed so as to be protruded from the connecting portions in a simple beam shape.

5. A glass run channel according to claim 1, wherein the shock absorption member is formed so as not to be at right angles to a movement direction of the windowpane, and is adapted to incline towards an inside the vehicle.

6. A glass run channel according to claim 1, wherein the shock absorption member is formed so as not to be at right angles to a movement direction of the windowpane, and is adapted to incline towards an outside of the vehicle.

7. A glass run channel assembly for a window frame of a vehicle body, the glass run channel assembly comprising:

an abutment glass run channel adapted to be mounted to a side of the window frame against which a windowpane is adapted to abut after the windowpane has moved, and

side part glass run channels adapted to be mounted substantially parallel to a movement direction of the windowpane at both sides of the abutment glass run channel;

wherein the abutment glass run channel and the side part glass run channels are assembled integrally with each other, the abutment glass run channel and side part glass run channel each having a main body portion including a pair of side wall portions and a base bottom portion connecting the pair of side wall portions and seal lips protruding from an opening edge side of the pair of side wall portions toward the base bottom portion;

wherein the abutment glass run channel has a shock absorption member adapted to be provided in a direction crossing a movement direction of the windowpane with a gap provided between the shock absorption member and the base bottom portion;

wherein low-friction material layers are provided integrally at a contact face of the shock absorption member that is adapted to come into contact with an edge of the windowpane and at least one of a back face of the contact face and a bottom face of the base bottom portion opposite the back face;

wherein the windowpane is displaced towards the outside of the vehicle when the windowpane contacts the shock absorption member;

wherein the side part glass run channel does not have a shock absorption member; and

wherein the abutment glass run channel and side part glass run channel are connected to each other at respective terminals by means of an additional connection member while maintaining a predetermined angle in a nonlinear manner.

8. A glass run channel assembly according to claim 7, wherein the shock absorption member is connected integrally with at least one of the base bottom portion and the side wall portion at least partly of a widthwise direction.

9. A glass run channel assembly according to claim 7, wherein the shock absorption member has a connecting portion connected integrally with at least one of the base bottom portion and the side wall portion, and is configured to protrude from the connecting portion in a cantilever beam shape.

10. A glass run channel assembly according to claim 7, wherein the shock absorption member has connecting portions connected integrally with at least one of the base bottom portion and the side wall portion, and is constructed so as to be protruded from the connecting portions in a simple beam shape.

11. A glass run channel assembly according to claim 7, wherein the shock absorption member is adapted so as not to be at right angles to the movement direction of the windowpane, and is adapted to incline to the inside of a vehicle.

12. A glass run channel assembly according to claim 7, wherein the shock absorption member is adapted so as not to at right angles to the movement direction of the windowpane, and is adapted to incline to the outside of a vehicle.

13. The glass run channel for a window frame of a vehicle according to claim 7, wherein said low friction material layers are made of a silicone compound.
