ABSTRACT:
An emergency locking device for a vehicle seat of the type wherein one lateral frame section of seat back frame is rotatably connected to a seat cushion frame, while another lateral frame section of seat back frame is connected thereto via one reclining device, the emergency locking device basically comprising an outwardly toothed lock element and an inwardly toothed lock element, which are provided at such one lateral frame section of seat back frame, with such an arrangement that a displacement of the seat back frame or a slight deformation of same, which is caused by a great load, will quickly bring one of the outwardly and inwardly toothed lock elements to engagement with another of them, to thereby lock that one lateral frame section in question against further serious deformation. The locking device is thus simplified in structure and light in weight.
