Abstract
Official abstract text for this publication.
A vehicle roll shade device is provided which includes a shade that opens and closes an inner opening of a roof; a roll shaft that winds the shade in a roll shape; a bearing member that pivotally supports the roll shaft; and an elastic member that is interposed between the roll shaft and the bearing member, wherein the bearing member includes: a lock mechanism that locks rotation of the roll shaft in a state of being urged to rotate in a shade rewinding direction by the elastic member; and a release mechanism that releases a locked state of the lock mechanism, and wherein a portion of the release mechanism comes in contact with a predetermined portion to be displaced when the bearing member is assembled to an assembling position, and the locked state of the lock mechanism is released in conjunction with the displacement.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle roll shade device comprising: a shade that opens and closes an inner opening of a roof; a roll shaft that winds the shade in a roll shape; a bearing member that pivotally supports the roll shaft; and an elastic member that is interposed between the roll shaft and the bearing member, wherein the bearing member includes: a lock mechanism that locks rotation of the roll shaft in a state of being urged to rotate in a shade rewinding direction by the elastic member; and a release mechanism that releases a locked state of the lock mechanism, and wherein a portion of the release mechanism comes in contact with a predetermined portion to be displaced when the bearing member is assembled to an assembling position, and the locked state of the lock mechanism is released in conjunction with the displacement. 2. The vehicle roll shade device according to claim 1 , wherein the lock mechanism includes an engaging portion that engages with an engaged portion of the roll shaft; and the release mechanism includes: a switch portion that comes in contact with the predetermined portion; and a flexible portion having the switch portion, and wherein the engaging portion of the lock mechanism is formed on the flexible portion of the release mechanism. 3. The vehicle roll shade device according to claim 2 , wherein the lock mechanism is made of a ratchet mechanism by which the engaging portion passes the engaged portion when the roll shaft rotates in a shade feeding direction, and the engaging portion engages with the engaged portion only when the roll shaft rotates in a shade rewinding direction.
