Claims7
An emergency-lock type retractor which is mounted to a child safety seat comprising:
- a rotatable drum,
- a seat belt connected to said drum,
- first means for controlling rotation of said drum to restrict said seat belt from being drawn out from said drum when a belt wound around said drum is pulled at a predetermined speed or higher,
- second means, set by an operator, for controlling rotation of said drum to restrict said seat belt from being drawn out and from being retracted, said second controlling means including:
- a gear rotatable with said drum;
- a locking pawl which engages said gear, said second controlling means causing said locking pawl to engage said gear;
- a drive plate formed integrally with said locking pawl;
- and
- a spring biased rotating plate adapted to be pushed against said drive plate so that said locking pawl engages said gear and thereby locks rotation of said rotatable drum.
