Abstract: A vehicle seat comprises a safety belt (24) having three anchoring points borne by the seat (10). The belt (24) has two straps--a diagonal strap (26) and a lap strap (28)--which are connected to the anchoring points. The diagonal strap (26) has an upper end (E1) and a lower end (E2) which is common to the lap strap (28). This upper end (E1) and this lower end (E2) are placed on opposite sides--left and right--of the seat, so that the diagonal strap (26) extends obliquely from top to bottom of the seat. The upper end (E1) and lower end (E2) of the diagonal strap (26) can be switched over between the left-hand side and the right-hand side of the seat. The seat (10) preferably comprises two upper belt turn fixtures--a left-hand one (40) and a right-hand one (42)--and the belt (24) has two catches (36,38) which are intended to be fastened into two buckles--a left-hand one (32) and a right-hand one (34)--borne by the seat.

Abstract: Process for producing a light steering wheel having a central hub, a peripheral rim and radial arms interconnecting the hub and the rim. The process is carried out by using a mould including a punch and a matrix having an impression in the shape of the steering wheel to be produced. The impression is at least partially filled with blanks of synthetic material charged with long fibers which are uninterrupted in each blank. The steering wheel, in the shape of the impression, is directly produced in one operation by stamping the blanks in the mould with the punch to shape the blanks into the steering wheel. The blanks are placed edgewise in the mould and are unshaped relative to the shape of the produced steering wheel.
