Abstract
In an automatic seat belt apparatus, a first tape is connected to a drive source. A second tape is connected to a slider and transmits a driving force from the drive source to the slider via the first tape. When a webbing is applied, a slide piece abuts a stopper. The slide piece moves relatively with respect to a lock plate against an urging force of a compression coil spring. Along with movement of the slide piece, the maintenance of the tapes at a connected position of the lock plate is cancelled. The lock plate rotates due to the urging force of the compression coil spring, and a separated position, at which the first tape and the second tape are separated, is maintained.
Claims21
An automatic seat belt apparatus comprising:
- a guide rail mounted on a vehicle body;
- a slider to which one end of a webbing is fixed, and which is provided so as to be movable along a longitudinal direction of said guide rail;
- a slider maintaining means freely engaging and disengaging from said slider, and engaging said slider at a webbing restraining position so as to maintain said slider;
- a maintaining position changing means able to change a maintaining position of said slider with respect to the vehicle body when said slider and said slider maintaining means are engaged;
- a first elongated member connected to a drive source;
- a second elongated member connected to said slider, and transferring a driving force from said drive source to said slider via said first elongated member;
- connecting means for connecting said first elongated member and said second elongated member, said connecting means having a first member, said first member being displaceable between a connected position, at which said first and second elongated members are connected, and a separated position, at which said first and second elongated members are separated;
- connecting means maintaining means movable between a first position, at which said first member of said connecting means is maintained at said connected position by said connecting means maintaining means, and a second position, at which said connecting means is movable to said separated position;
- urging means for urging said first member of said connecting means in a direction of being displaced to said separated position, and for urging said connecting means maintaining means such that said connecting means maintaining means is positioned at said first position;
- and
- operating means provided in a vicinity of said webbing restraining position, for moving said connecting means maintaining means to said second position against an urging force of said urging means by movement of said slider to said webbing restraining position.
