To prevent passengers sliding or 'submarining' under a safety belt, the front portion of the squab 3 of a vehicle seat 1 has a cylindrical airtight cell 7 filled with resilient foam. The foam ensures that the seat is comfortable when the cell is deflated and vent passage 11 allows the cell to compress when sat upon. A gas generator 9 inflates the cell via passage 8 in response to a signal from accident detection means 10 and can either enlarge the cell or make it rigid without enlargement. Embodiments include three serially linked cells (Fig. 5) or a single large cell forming the front section of the squab (Fig. 6). |
