  • Patent number: 4580838
    Abstract: A hinge fitting for an adjustable seat has a single rotatable handle by ms of which the back rest can be tilted and the height of the seat portion adjusted. The handle is connected to a shaft which can be selectively coupled to one of two eccentrics mounted on an axle which passes through the two hinge parts and one end of a pivotable seat support. One eccentric is coupled to one hinge part which has spur gear areas engaging inner toothings on the other hinge part. Rotation of this eccentric causes the inclination of the back rest to be adjusted. The other eccentric is coupled to a portion of the end of the seat support which is constructed as a three-stage hollow piston having inner toothings engaging spur gear areas on the adjacent seat hinge part. Rotation of this eccentric causes the height of the seat to be adjusted.

  • Patent number: 4573739
    Abstract: Hinge structures are disclosed which are useful in seats with adjustable krests, the structures including a gear unit (6, 8) in which indented and protruding tooth systems (6a, 8a) are punched into the hinge pieces using the precision blanking process, the diameter as well as the tooth contour of the protruding tooth system (8a) being at least partially smaller than the diameter and the tooth contour of the associated indented tooth system (6a) so that material can then flow from the unused tooth system produced during precision blanking and into the effective tooth system, thus enlarging the tooth width (b) of the effective tooth system to be greater than the thickness (d) of the initial material. See FIGS. 4a and 5a.

  • Patent number: 4398751
    Abstract: A vehicle safety belt link point assembly for attachment to a pillar of the vehicle at a location adjacent the shoulder of a vehicle occupant, includes a slotted guide with one link provided with a series of locking openings. The guide is secured to the pillar. A slide member is mounted on the guide and has one limb lying adjacent and parallel to the limb of the guide. The slide member limb has one opening which can be made coincident with any of the openings of the guide member limb. A slide piece carries a link point for receiving the belt webbing and is movable in the slot of the guide. A link is movable with the slide piece and carries a projection which can engage in a selected opening of the guide limb and with the opening of the slide member to lock the device.

  • Patent number: 4327570
    Abstract: For bending strip material into toothed shape, the strip is introduced once into a pair of toothed jaws and a bending member is moved from one end position to another to bend the strip about one end tooth, one end flank of which is exposed. The strip is removed and then similarly bent about another end tooth, in a preferably mirror-image arranged part of the apparatus, in an opposite bending direction, thereby to form a tooth in the strip. The bending steps are repeated as often as necessary.The invention is particularly applicable to the forming of a toothed band from a plane sheet metal strip.

  • Patent number: 4063776
    Abstract: A seat for an automobile or other vehicle includes a seat part and an adjable back-rest part. The two parts are connected pivotally by a linkage which includes an eccentric disc having a large ratio of diameter to thickness. The disc engages in a recess in the back-rest part and is mounted on the seat part for rotation whereby the inclination of the two parts can be adjusted without relative translational movement between the two parts.
