Abstract: A vehicle seat reinforcement device includes a leg portion mounted on a floor panel, a seat cushion frame slidably mounted on the leg portion, and a load reinforcing structure connected between the leg portion and the seat cushion frame, wherein when a seat belt anchorage load is transferred to the seat cushion frame, the seat cushion frame is locked to the leg portion by the load reinforcing structure.

Abstract: A linear actuator having an elastic injection-molded frame includes a yoke, a permanent magnet attached to a bottom surface of the yoke at a distance from a side surface of the yoke, a top plate attached to a top surface of the permanent magnet, a frame coupled to an outer periphery of the yoke and injection-molded with an elastic material, a protector disposed on the frame, and a coil secured to the protector, with a lower end positioned between the permanent magnet and the side surface of the yoke. The frame includes a yoke coupling portion coupled to the yoke, a fixing portion spaced apart from the yoke coupling portion and coupled to the protector, and two or more bridges for elastically connecting the yoke coupling portion and the fixing portion.

Abstract: An automatic winding device includes a lower casing having a shaft, a bobbin rotatably disposed on the shaft with a wire wound around the bobbin, a spring to provide a rotational force to the bobbin, a track cover coupled to the bobbin to rotate with the bobbin and having a track formed thereon, a pin structure positioned between the bobbin and track cover and having a pin for controlling bobbin rotation, and a pin guide for guiding linear motion of the pin structure. The track cover includes an inner track, an outer track spaced apart from the inner track, a connection track for connecting the inner and outer tracks, and a stop track for connecting the inner and outer tracks. The stop track has a bent portion for stopping the pin. An end of the connection track near the outer track is connected to the outer track and stop track.
