Title: Improvements relating to Rear Axle Suspensions
IPC: B60G3/22
Filed: 1968-08-12
Abstract: 1,198,350. Vehicle rear axle suspensions. DAIMLER-BENZ A.G. 12 Aug., 1968 [16 Aug., 1967], No. 38363/68. Heading B7D. A vehicle rear axle suspension comprises a pair of longitudinal wheel control arms pivotally mounted on the wheel carrier offset from the wheel axis, one extending forwardly, and the other rearwardly of the wheel, and a brake stator pivotally mounted in the wheel carrier in order to compensate brake dive, and braced upon the forward wheel control arm by means of a connecting member, the second control arm being obliquely oriented with respect to the first arm so that, in side elevation, the lines of the control arms passing through their pivot points intersect in a point behind the axle in the central springing position of the vehicle in order to compensate front end lift. The rear wheels 11, Fig. 1, are independently suspended by means of a lower control arm 12 and an upper arm 13, pivotally connected to the wheel carrier 14 at 17 and 18 by pivot pins 17a, 18a, Fig. 3, respectively. The arm 12 is constructed as a wish-bone or fork-like arm and is pivotally mounted through bearings 15, (16), Fig. 2 (not shown), and rubber bushings to the frame 10, and arm 13 is mounted pivotally on the frame 10 at 20. The upper arms 13 on both sides of the vehicle may be mutually connected to a torsion bar. The wheel hub 25 and brake drum 26 are rigidly connected to a flange 24 on the stub shaft 23. The brake shoes 27 are mounted on a brake stator 28, the hub 28a of which is inserted axially between the wheel carrier 14 and stub shaft 23 and is mounted to be rotatable with respect to both, on roller bearings 29, 30, needle bearings 31, 32 and a thrust bearing 33. Towards the rear of the wheel the stator hub 28a is connected to a brake bearing 28b which supports the brake shoes 27, and at its forward end the stator has an arm 35 which is braced on the lower control arm 12 by means of a member 36. When the vehicle is braked, the wheel 11 will tend to continue to rotate in the direction of arrow y, producing a torque on the brake stator, whose arm 35 will thus exert, through the arm 36, a downward pressure on control arm 12 which is braced at 17, so tending to draw the vehicle structure downwards, which counteracts the lifting of the rear of the vehicle, hence brake dive is compensated.

Title: Upholstered seat construction
Inventor: ELLINGHAUS WILHELM
IPC: A47C7/20
Filed: 1985-03-09
Abstract: An upholstered seat, for example for a motor vehicle, has a moulded plastics frame which may form the foundation both of the seat cushion and the backrest. The frame has a peripheral surround 18 and a sprung platform or diaphragm 26 extending across the frame. The platform is formed integrally with the surround so that the spring webs 26 are made of the same plastics material as the frame. The surround is designed as a structural beam so as to have sufficient inherent strength to require no external stiffening. The seat is formed by inserting a sheet of covering material into one half of a mould, inserting the plastics frame into the other half and injecting polyurethane foam into the closed mould. In one embodiment, the sprung platform is formed by a continuous web.   <IMAGE>

Title: An extractor for piercing elastic closure means
Inventor: SCHACHT BODO
IPC: A61M5/162
Filed: 1985-09-25
Abstract: The extractor has a puncturing spike (11) for piercing the elastic membrane of a container. The gripping piece (10) is designed on one side as a thumb recess (14) with lateral limits (15) and on the opposing side as a gripping surface (18) without lateral limits. The thumb recess (14) and the gripping surface (18) have ascending regions (17, 19) respectively which each run in an arc of approximately 90 DEG and define the flange (16) forming the front end of the gripping piece. While the thumb is inserted longitudinally into the thumb recess (14), the second section of the index finger is placed transversely against the ascending region (19) of the gripping surface (18). In this way, a high force of insertion can be exerted on the gripping piece (10) without the risk of sliding off and without the need to press the thumb and index finger together unnecessarily. <IMAGE>
