Abstract: A shock absorbing steering column apparatus comprise a steering column member admitting an insertion of a steering shaft, and a shock absorbing member for permitting the steering column member to displace in an axial direction while being plastically deformed by an impact load applied in the axial direction of the steering column member. The steering column member and the shock absorbing member are integrally formed of a non-ferrous metal.

Abstract: For rapid inflation of a gas bag a pressurized gas container has an outlet opening closed by a closure disc adapted to be blown off to free the outlet opening. An intermediate housing has an interior space which is divided by the closure disc into a pressure chamber provided with inlet openings for gaseous combustion products of a propellant charge and an outflow space having outlet openings for a gas mixture for filling the gas bag. A pair of propellant charges are separated from each other in a housing surrounding the intermediate housing. An accommodation space for the first propellant charge is directly connected with the pressure chamber through an open conduit. A conduit for communication of an accommodation space for the second propellant charge with the pressure chamber is closed by a closure element.

Abstract: A heavy duty suspension system for multiple axle over-the-road semi trailers. A rigid frame for the suspension includes beams on opposite sides which are connected with the trailer body. Hangers receive the front ends of spring beams to which the axles are connected. Torque arms connect the hangers with the axles. Behind the axles, air cushions are interposed between the spring beams and frame to provide an air ride. A transverse track rod is provided behind each axle to accept laterally applied loads. Each track rod is pivoted at one end to the back of one spring beam and at the other end to a track rod hanger suspended from the frame.
