US 5,397,166 A · Light-weight seat for motor vehicles

Abstract

Many seats are of complicated construction and are therefore heavy and expensive. To obviate these disadvantages, a self-springable seat member on which a cushion is placed, is mounted in its front region on a bridge which is mounted on the outside on the upper parts of the running or sliding rails. Connections for a backrest are secured to the rear regions of the upper parts.

#Referring to FIGS. 1 and 2, in a light-weight seat 1, of which the cushion is not shown in the drawing, running or sliding rails 2 are arranged on both sides with their lower parts 11 on the floor of the vehicle and a bridge 4 is securely connected in front to the two upper parts 3 through its outer supports 5. A self-springable seat member 8 is fixed by its non-springable front part 7 to a cross beam 6 of the bridge 4 and has impressed stiffening corrugations 9 distributed across its width that become weaker and/or run out towards the rear so as to give a suitable spring constant over the length of the seat. The cross beam 6 and the outer supports 5 can be pressed steel sheet parts and have a top-hat or U-shaped cross-section.

#Connections or a backrest mounting 10 for the backrest are arranged on the rear regions of the upper parts 3.

#For lateral outer connection or support of the cushion, external cushion support hoops 13 are provided that are connected at the front to the sides of the seat member 8 and also at the back - as shown - to the backrest connection 10, and or else as shown in FIG. their second attachment can be made to the upper part 3 of the running or sliding rails 2 as shown by dashed lines 20. Alternatively, the hoops 13 can be secured laterally outside to the bridge 4.
