  • Patent number: 4810005
    Abstract: The bottom wall (12) of a rectangular housing (10) comprises a trough-like depression (14) which is sealed on the inside of the housing (10) by a cover (22) provided with a securing flange (22A). A propellant charge (42) is introduced into the trough-like depression (14). The housing (10) is sealed at its front side by a covering formed by two pivotal foamed material plates (30, 32). In the interior of the housing (10) a folded gas bag (26) is accommodated which is inflated by the gases forming on combustion of the propellant charge (42) and flowing through gas passage openings of the cover (22) into the interior of the gas bag (26). Since the propellant charge (42) can be introduced directly or using a simple capsule housing of plastic into the interior of the trough (14) a separate and involved gas generator housing can be dispensed with.

  • Patent number: 4802689
    Abstract: The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes. For this purpose the rigid axle is guided on each side by a pair of guiding control arms which determine, for its wheel axis, a pivot axis about which the wheel axis is movable by means of a guide arm retained on the vehicle body in the sense of the positive oblique springing during inward spring stroke movements.

  • Patent number: 4789038
    Abstract: An axle weight distribution controller for maintaining the weight borne by the steering axle of a load-carrying vehicle. A load transducer attached to the steering axle produces an electrical signal that is compared with signals representing desired minimum and maximum loads to be borne by the steering axle. If the load borne by the steering axle falls outside of the predetermined load interval, the pressure in an air spring supporting a third axle is adjusted so as to redistribute the weight borne by each of the other axles in the vehicle and to bring the load borne by the steering axle within desired limits.

  • Patent number: 4787646
    Abstract: The riding mower chassis of this invention has laterally spaced front traction wheels, attachment fittings for a mower that rides in front of those wheels, and laterally spaced rear wheels that can float up and down to accommodate terrain irregularities, For such floating a rear axle has at its midpoint a pivot connection with the frame whereby its ends can swing up and down, and the rear wheels are mounted on its ends for rotation and for swiveling relative to it. Swiveling of the rear wheels is controlled by an operator seated on the chassis from a steering wheel at its front. A pair of cable stretches that have their front ends connected with the steering wheel shaft extend rearwardly at the underside of the chassis frame to connections with a steering linkage on the rear axle.
