Abstract
A brake device for a vehicle seat, which includes a tooth plate installed on an unlock member and coupled to a pinion shaft in a serration manner to constrain rotation of the pinion shaft. Therefore, even when the rotational constraint force by brake rollers is reduced due to the repeated loading, the rotation of the pinion shaft is reliably suppressed by the tooth plate, thereby preventing seat sagging.

- a brake ring mounted on the other side of the housing;
- a pinion shaft rotatably installed in the housing through the brake ring;
- a brake member installed between the brake ring and the pinion shaft and constraining the pinion shaft with respect to the brake ring or releasing constraint of the pinion shaft;
- and
- a tooth plate installed in the unlock member and constraining rotation of the pinion shaft.
