Abstract

To provide a power window apparatus which can reliably actuate an anti-pinching mechanism even in a window provided with a side visor, a cord switch operable in response to a specific external force is mounted in a joining part of a side visor between a window frame and the side visor. The cord switch senses the external force acting on the side visor, reliably detecting a foreign object pinched between a window glass and the side visor.

Claims

1. A power window apparatus for a vehicle, comprising:

a window body for opening and closing a window opening formed by a window frame;

a side visor molded in a substantial plate, said side visor provided along an exterior periphery of said window frame and disposed on an exterior surface of said window frame, opposite to an interior of said vehicle, for providing shade to the periphery of said window opening;

a sensing switch disposed on an exterior side of said window frame, opposite to said interior of said vehicle, for sensing an external force acting on said side visor; and

window closing operation stopping member for stopping a closing motion of said window body when the external force sensed by said sensing switch exceeds a preset value.

2. A power window apparatus as claimed in claim 1, wherein:

said sensing switch is located in a joining part where said side visor is attached to said window frame.

3. A power window apparatus as claimed in claim 2, further comprising:

a cover member joined to said window frame for holding said side visor slidably in an up-and-down direction and covering said joining part from above;

said sensing switch being located within said cover member.

4. A power window apparatus as claimed in claim 2, wherein said sensing switch includes:

a pair of conducting members extended along said window frame and disposed face to face at a predetermined spacing therebetween;

a holding member for holding said pair of conducting members; and

a displacement member positioned displaceably with respect to said holding member and to said pair of conducting members,

wherein said holding member is connected to one of said window frame and said side visor, and said displacement member is connected to the other of said window frame and said side visor.

5. A power window apparatus switching device as claimed in claim 4, wherein:

said pair of conducting members are disposed face to face in a direction in which said window body is opened and closed; and

said displacement member being provided with displacement restricting member for restricting the displacement of said displacement member in a direction intersecting the direction in which said window body is open and closed.

6. A power window apparatus as claimed in claim 1, wherein:

said sensing switch has a pair of conducting members extended along said window frame and disposed face to face across a predetermined space therebetween; and

an insulating holding member made of a porous elastic material for holding said pair of conducting members to thereby define said space therebetween.

7. A power window apparatus as claimed in claim 6, wherein:

said insulating holding member is made of at least one of the materials such as polyurethane and polyethylene.

8. A power window apparatus, comprising:

a window body for opening and closing a window opening formed in a window frame;

a side visor provided along an exterior periphery of said window frame, for providing shade to a periphery of said window opening;

a sensing switch for sensing an external force acting on said side visor;

a window body driving member for driving said window body;

a load detecting member for detecting a driving load of said window body driving member; and

window closing operation stopping member for stopping the movement of said window body toward closing when the external force sensed by said sensing switch exceeds a preset value and also when a detection value detected by said load detecting member exceeds a preset value.

9. A power window apparatus, comprising:

a window body for opening and closing said window opening formed in said window frame;

a side visor provided along an exterior periphery of said window frame for providing shade to a periphery of said window opening;

a first sensing switch for sensing an external force acting on said side visor;

a second sensing switch disposed on said window frame for sensing an external force acting on said window frame;

a window body driving member for driving said window body;

a load detecting member for detecting a driving load of said window body driving member; and

window closing operation stopping means for stopping the movement of said window body toward closing when at least one of said first sensing switch and said second sensing switch exceeds a preset value and a detection value detected by said load detecting member exceeds a preset value.

10. A power window apparatus as claimed in claim 9, wherein:

said second sensing switch is disposed in a weatherstrip installed along a periphery of said window frame.

11. A side visor for a window frame, comprising:

a side visor body portion molded in a substantial plate to be attached to an exterior surface of said window frame, opposite to an interior of a vehicle, for shading a periphery of a window opening formed in said window frame; and

a sensing switch embedded in said side visor body portion for sensing an external force acting on said side visor body portion, said sensing switch being located at said exterior surface of said window frame, opposite to said interior of said vehicle, when said visor body portion is attached to said window frame.

12. A side visor as claimed in claim 11, wherein:

said sensing switch is located in a joining part of said side visor body portion between said window frame and said side visor body portion.

13. A side visor as claimed in claim 11, wherein said sensing switch has:

a pair of conducting members extended along a part corresponding to said window frame and disposed face to face across a predetermined space therebetween; and

an insulating holding member made of a porous elastic material for holding said pair of conducting members to form said space therebetween.

14. A side visor as claimed in claim 13, wherein:

said insulating holding member is made of at least one of the materials such as polyurethane and polyethylene.

15. A side visor as claimed in claim 11, wherein:

said sensing switch is located at an edge portion of said side visor body portion which is opposite to a joining part of said visor body portion between said window frame and said side visor body portion.

16. A side visor as claimed in claim 15, wherein said sensing switch has:

a plurality of conducting members extended spirally along a part corresponding to said window frame and disposed face to face across a predetermined space thereamong; and

an insulating holding member attached to said edge portion and holding said conducting members therein.
