Abstract: The present application pertains to a seat pad particularly for motor vehicles seats, with a core portion made of expanded plastics material. The upper side of the core portion facing the seat surface is provided with channel-like grooves, so that the geometry of the remaining core portion allows an optimum distribution of the seat pressure because of the good adaptation to the human anatomy.

Abstract: A seat back for an automotive seat with an integrated protective device and a process for preventing injuries to a seat occupant caused by an accident in the event of a rear-end impact. The seat back features a bottom seat-back part and a top seat-back part that, by means of a torque, pivots around an axis in the seat back that is perpendicular to the longitudinal axis of the vehicle, out of a position of standard use and into a safety position. To improve the efficiency of such a seat back, it is proposed that the protective device features a device that generates the torque regardless whether the automotive seat is occupied, and means for detecting a rear-end impact, which are actively linked with the torque-generating device in such a way that the device is activated in the event of a rear-end impact and the swinging movement is started.

Abstract: Backrests of motor vehicle seats are attached so that their inclination can be adjusted and fixed by way of hinge mountings 1 with eccentric planetary gears 2, the rolling bodies of which are made by extrusion moulding.To increase the fracture resistance of the tooth systems, the teeth of the outer and inner tooth systems 5 and 6 are both attached laterally through strong annular material regions 7 and 8 respectively which avoid stress concentrations, and also, to produce a good lateral engagement relationship of the tooth systems, the rolling bodies 3 and 4 are mounted on the axis 9 in a manner effective to prevent tilting, namely by extending the bearing surfaces through hubs 10 and 11 and spacing the bearing faces of the two rolling bodies equidistant from the centre 12 of the external and internal tooth systems 5 and 6 respectively.

Abstract: A sitting section of a vehicle seat which provides comfort for an occupant of the seat and affords protection against the occupant sliding forwards in the event of a crash, the sitting section having a frame with a seat shell having a selected natural vibration and a forward arched section and a section rearward of the arched section which is adapted to oscillate freely and is reinforced with corrugations, the seat shell sloping downwards towards the rear at an angle of about 15.degree., and the seat shell having relatively thin upholstery fitted thereover.

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.

Abstract: A tilt-away system for front seats of vehicles for permitting the entire front seat to be moved as far as possible out of the entry and exit region of the vehicle includes a seat frame front support assembly including a support stand which supports the front portion of the seat frame, a seat frame rear support assembly including link arms on each side of the seat frame, the link arms having forward ends pivotally secured to travellers which are displaceably mounted in rails and rearward ends connected to the rearward portion of the seat frame and being locked in a use position for the seat by a link arm locking mechanism, the link arms being adapted to be pivoted forwardly and upwardly to tilt the seat forwardly after it has been moved forwardly on the rails to a position intermediate the use and access positions, and a release mechanism for releasing the front portion of the seat frame from the support stand and the link arm locking mechanism in one operation so that the front seat can be moved forward to th

Abstract: Running rails for securing a motor vehicle seat to a motor vehicle and permitting fore and aft movement of the seat in the direction of the longitudinal axis of the vehicle, including cooperating upper and lower rails each consisting only one profiled member, the lower rail having a generally U-shaped cross section with upwardly extending limbs having upper ends which are bent over forming inwardly extending arcuate parts which define first portions of first and second ball bearing raceways, the upper rail having a wedge shaped portion defining second portions of the first and second ball bearing raceways, and bottom web portions of the upper and lower rails being spaced apart defining a track for roller bearings.

Abstract: An upholstery support for the back rest of a vehicle seat, particularly a motor vehicle seat, is disclosed. The support comprises two half-shells connected with each other along at least a portion of their edges and form two hollow box-like arms (4) which extend downward from an upper area (3) of the upholstery support, whereby at least in one of the two half-shells (2) troughs (b 6, 7, 10) are provided, the troughs (6, 7) follow two lines that cross in the upper area and end at a distance from the crossing point. Adjacent to the crossing point, the ends of at least two of the troughs (6, 7) are connected with each other by a connecting element (13) which has a trough-like central zone between two edge zones adjacent to the half-shell (1) and securely connected therewith, which central zone bridges and stiffens the trough-less intermediate space between the trough ends to be connected with each other.

Abstract: A plastic body for use in vehicle seats, having at least one element joined therewith to form a single structural unit, which element is made from a material having different physical characteristics than those of the plastic. The element is formed as a dampening element made from a plastically deformable metal securely connected with the plastic body and/or as an insert in the plastic body. Between the dampening element and/or insert and the plastic body an intermediate layer is provided, the intermediate layer being made from a material that permits relative movements between the plastic body and the dampening element and/or insert.

Abstract: Continuously adjustable pivoted hinge, such as employed for automotive vehicle recliner seat back, wherein a toothed sector on one hinge element is retained by a toothed pawl on the other which has freedom of mounting connection at least equal to the pitch of one tooth in order to accommodate full tooth engagement for any continuously variable relative position of the sector. A pair of pivotally anchored cam elements engage angularly related cam surfaces on the pawl after its full tooth engagement with the sector. Variable travel of cam surface to accommodate fully engaged prepositioned pawl with self-locking angle resisting pawl displacement in either angular direction from sector tooth pressure, is sufficient to accommodate at least one tooth displacement of the pawl in order to lock the pawl in any position of initial full tooth engagement. The pawl is pivotally mounted at the hinge pivot with a radial slot to accommodate tooth disengagement.

Abstract: The frame of the seat in a motor vehicle has a base for the cushion which carries the weight of the occupant and a back rest which carries the cushion for the back of the occupant. The back rest has two upwardly extending parallel frame members and a connector between the upper ends of the frame members. The upper end of one frame member carries a takeup reel for the safety belt whose latch plate can be inserted into a buckle adjacent the lower end of the other frame member. When the belt is applied and is tensioned, such as in the event of an accident, it applies to the one frame member a force acting diagonally of the back rest and tending to bend the one frame member forwardly and toward the other side of the seat. The cross-sectional outline of the one frame member and the orientation of such cross-sectional outline are selected in such a way that the one frame member offers maximum resistance to deformation by the belt in the direction in which the belt acts thereon in the event of an accident.
