Abstract: A folding seat for a vehicle comprises a strap assembly (5) provided on the bottom of a seat cushion (2) and including a first belt member (50) providing a connection between the bottom of the seat cushion (2) and the back of the seat back (3) when the seat is folded, and a second belt member (51) cooperative with the first belt member (50) to fasten and retain the head rest body (41) when the seat is folded. The strap assembly (5) can be used to retain together all the seat components including the head rest (4) in a single compact folded configuration, thus providing over the rear of the seat back (3) an extra space adding to the existing space for baggage loading or other purposes.
