Abstract

PURPOSE:To obtain a seat back frame which can bear a heavy load acting on the shoulder anchor point on plunging forward by fixing an inner subsideframe at the sideframe of a triangular reinforcing frame to form a highly rigid side frame having a hollow part. CONSTITUTION:A reinforcing frame 17 is arranged at the back of the main frame 12 welded with the frame. The upper part of the inner subside frame 22 is twisted toward the buckle of the seat cushion frame and also the upper part of the side member 19 of reinforcing frame 17 is twisted to the same direction. The hollow chamber made by the side member 19 of the reinforcing frame 17 and the upper part of the inner subside frame 22 is nearly square to arrange a retractor. The heavy load acting on the retractor in front and behind is received by the main frame 12, the reinforcing frame 17 and the inner subside frame 22, hence, the seat back frame 1 is not deformed.

Seat belts have become essential. Seatbelts are equipped with retractors on the pillars on the side of the vehicle (in normal times, the seatbelts can be moved in and out freely to ensure the occupant's freedom of movement.
There are two types of belt-integrated seat devices: one in which the belt is tightened only in an emergency to restrain the occupant in the seat, and the other is a belt-integrated seat device in which the retractor is directly fixed to the seat back frame.
