Definitions

  • ABSTRACT A seat, particularly for automotive vehicles, which comprises a seat-cushion frame adjustable in height and inclination.
  • the seat has two pairs of extension links, and a seat-base frame, as well as toggle-lever links, and transversely-extending connecting rods.
  • the seat-cushion frame is connected via the two pairs of extension links with the seat-base frame.
  • the extension links are supported via the toggle lever links on the seat-base frame and are connected in pairs with each other by the transversely-extending connecting rods.
  • Spring means urge the connecting rods into a raised position of the seat-cushion frame and are displaceably guided in slots in the seat-base frame.
  • a releaseable tooth-engagement lock, including teeth, are disposed within the region of the slots between each of the connecting rods and the seat-base frame such that the teeth are directed parallel to the plane of the slot.
  • the present invention relates to a seat, particularly for automotive vehicles, with a seat-cushion frame, which is adjustable in height and inclination and is connected with the seat-base frame by two pairs of extension links, supported by toggles links on the seat-base frame and are connected in pairs with each other by a transversely extending connecting rod, the connecting rod being urged by a spring into the raised position of the seat-cushion frame.
  • the operating levers of a locking means which makes possible a stepwise vertical displacement, also protrude laterally from the seat-base frame, so that the entire possible range of adjustment cannot be utilized. Furthermore, additional space for movement is required forthe release of the upward swingable detent jaws which engage in annular groves on detent pins, one of which is seated on each of the displaceable connecting rods.
  • the seat of this invention is characterized by simple and rapid operation, is of uncomplicated construction, of extremely low structural height, and can be installed in practically all current models of cars and special vehicles.
  • a dependable toothed locking which can be released by a twist of the hand is employed.
  • the locking teeth are directed parallel to the plane of a longitudinal slot.
  • the invention employs a pin urged in the direction of rotation by a spring and supported in the preferably round tubular connecting rods, the pin being continued by an operating lever, which lies on the outside of the seat-base frame.
  • the pin has two diametrically opposite detent teeth which engage in oblique position to the slot on opposing toothed slats extending parallel to the edges of the slot.
  • the pins are advantageously formed at the same time as the longitudinal slot-slide axes of the extension links.
  • the spring force is applied by a torsion spring arranged in the inside of the tubular connecting rods. This tension spring acts in the direction towards the basic position of the operating lever and accordingly presses the sides of the detent teeth against the corresponding sides of the stationary teeth. In order to release the basic detent position, it is therefore merely necessary to swing the detent teeth by an amount equal to the length of the side of the adjoining tooth. This corresponds to only a few degrees.
  • the pin can be shifted in the longitudinal slot and the adjustment of the height and inclination of the seat-cushion frame thus brought about.
  • This displacement is effected with the assistance of a stored force.
  • a corresponding force-storage spring therefore urges the connecting rods in the direction apart from each other.
  • the angle of the release swing of the operating lever is advantageously in the direction towards the ends of the longitudinal slot, which ends face each other. In this way an actuating region of limited space requirement is provided, which makes prolonged hunting unnecessary.
  • the driver can reach into the actuating range. He can thereby easily determine, by touch, which operating lever is to be manipulated for the rear displacement section and which for the front displacement section.
  • the displacement means themselves are also of a very simple design.
  • the toothed slats consist of stamped plates having a window-like opening with detent teeth lying in the edge region.
  • the plates can be attached by welding, riveted or otherwise.
  • They bring about a stabilizing of the section of the frame which is weakened by the longitudinal slot.
  • the rotation of the pin is limited by a stop, in order to prevent the teeth engaging into the opposite toothing in case of too large a path of swing of the operating levers.
  • the limitation by stop is therefore of such a nature that the detent teeth of the pins extend, in the one stop position, approximately in the longitudinal central plane of the slot.
  • a favorable structural shape has the connecting rods provided on one side with a toothed-slat jaw, with which there is associated a jaw extending parallel to the longitudinal slot which is provided with a mating toothedslat and is swingable in the transverse direction against spring action.
  • FIG. 1 is a side elevation of the car seat, designed in accordance with the present invention
  • FIG. 2 is a front elevation thereof
  • FIG. 3 is a fragmentary view, on a larger scale, of the joint between the seat cushion, seen in the same direction as FIG. 1 and the back-rest cushion;
  • FIG. 4 is a section along the line IV-IV of FIG. 3;
  • FIG. 5 is a fragmentary showing of the height and inclination adjustment device with the seat-base frame lowered
  • FIG. 6 is a corresponding view with the seat-base frame raised
  • FIG. 7 is a top plan view of the seat-base frame
  • FIG. 8 is a variation of the height-and inclinationadjusting device.
  • FIG. 9 is a section along the line IX-IX of FIG. 8.
  • the car seat shown has a frame 2 which bears a cushion 1 and from which there extends at the rear two upward directed checks 3, which carry bearing pins 4 for the back-rest frame 6 which is also covered by a cushion 5.
  • the back-rest frame 6 is mounted for a swinging motion around the pin 4.
  • the desired position of inclination can be locked via a mechanism 7 (FIG. 3).
  • the latter consists of two intermeshing toothed jaws, namely a displaceably mounted slidepiece toothed jaw 10, which can be released via a control pin 8 by a handle 9 and the mating toothedjaw 11 on the frame side.
  • the toothed jaw is pulled downward by means of the control pin 8 which passes through an arcuate slot 3' in the check 3 and extends into a control slot of the jaw 12, the guide pin, extending in the basic position beyond the deadcenter position x-x, supports the slidepiece toothed jaw 10, which is acted on by a return spring 13.
  • the seat-cushion frame is supported at the front and the rear by extension links 14.
  • the latter are arranged in pairs and are connected via link pins 15 to the seat cushion frame 2.
  • the pivot connection on the seat-base frame side is obtained by means of pins 1' one of which is shown at 16 in FIGS. 5 and 6, each of which passes through a separate longitudinal slot 17 in the seat-base frame 18; each pin is formed at one end into a bent operating lever 19.
  • the preferably bent end of the operating lever 19 bears a handle 19'.
  • Both the pins 16 lying on the side of the operating lever 19 and the opposite pin 16 are supported in a rod 20 which rigidly connects the extension links 14 with each other.
  • the correspondingly tubular connecting rod 20 furthermore receives a torsion spring, which is secured on the pin 21.
  • the torsion spring is so arranged under pre-tension, that it urges the pin 16 having the operating handle in the direction indicated by the arrow y (see FIG. 6).
  • toggle links 23 acting as supporting lever. These links are pivoted on the one side to the pin 24 of the seat-base frame 18 and on the other side via pivot pins 25 to the extension links 14, approximately in the central section between the pins 15 and 16.
  • the toggle links 23 are also firmly connected with each other on the seat-base side by a tubular connecting rod, so that the load of the seat is transferred uniformly to the adjacent extension links.
  • These connecting rods are designated 26 (FIG. 7 They extend parallel to the pins 16.
  • a pin 16 is displaceable in the slot 17 by an amount corresponding to the length of the slot and thus produces a change in height and/or inclination of the seat surface.
  • This pin can be locked in position by tooth engagement between a connecting rod 20 and the seatbase frame 18.
  • the pin 16 mounted in the tubular connecting rod 20 has two detent teeth 27 and 28 lying diametrically opposite each other. These teeth engage in tooth gaps 29 of correspondingly associated toothed slats 30. The latter extend in the direct vicinity of the slot edge 17, on the outside of the frame 18.
  • the teeth 31 of the toothed slats extend accordingly in a plane parallel to the plane of the slot.
  • the tooth tips 31' which face each other terminate directly at the height of the slot edge 17'.
  • the detent teeth 27, 28 have a width B which corresponds to that of the tooth flanks 31".
  • the tooth depth is so dimensioned that it does not extend beyond the thickness of the toothed slats 30 which, for reasons of ease in manufacture, are advantageously designed in the form of a continuous plate 32.
  • the plate 32 can be held in position, for instance, by welding.
  • it at the same time also constitutes an advantageous reinforcement of the region of the frame which is weakened by the slot. Since the detent teeth 27, 28 extend for all practical purposes only by an amount equal to the width of the tooth into the spaces 29 only a slight actuating path results, so that the release position can be brought about easily and without diverting the attention of the driver.
  • the basic detent position is obtained automatically upon release of the operating lever 19.
  • the pin 16 which are at the same time the slot-slide pins of the tension links are immediately released. If such a displacement is effected towards the right (see FIG. 4), this results in the lowering of the front edge of the seat. If such an actuation is effected on the rightside pin 16 (see FIG. 2), then the rear end of the seat is also lowered either at the same time or following same.
  • one or the other of the pairs of extension links is left in its supporting position.
  • transverse pin 33 shown in FIG. 7.
  • the latter is driven into the pin 16 and extends into a transverse slot 34 which is provided in the connecting rod 20 and forms the corresponding end stop.
  • the length of the transverse slot 33 is dimensioned with due consideration of the connectrods 20 own rotation.
  • the width of the longitudinal slot 17 is so selected, that it provides sufficient play for the deviation which varies in accordance with the vertical position of the frame 2, but is still tolerable, so that the detent teeth in release position extend approximately in the longitudinal center of the slot or slots, respectively.
  • the release direction of swing of the operating levers 19 lies in the direction of the slot ends 17" which face each other. Accordingly an opposite alignment of the operating levers is established also in the basic locked position.
  • This has in particular the advantage, that the driver can easily determine by touch whether it is the front or the rear lever of the adjusting handle.
  • Thedisplaceable connecting rods are acted on by an expanding force-storage spring 35.
  • This is a leaf spring which is shaped into a ring. In its central region it is placed over pins 36 extending from the inside of the lengthwise arms of the seat-base frame 18.
  • the spring has corresponding holes.
  • the force-storage spring acts via supporting bearings 37 on the connecting rods 20. In this case also this spring is merely placed over pins 36.
  • the spring force acts in the direction to change the height, so that by a change in weight of the person sitting in the seat, a raising of this half of the seat or of the other half of the seat takes place by means of the force-storage spring.
  • Extension links and toggle lever links also are smaller than this vertical dimension, so that only the ends of the extension links which are on the seat-cushion frame side extend also in order to avoid self-locking beyond the upper edge 18' of the frame, whereby an extremely compact construction with optimum stability is obtained.
  • each connecting rod 20 or of the pins 16 rigid provided with a toothed slat jaw 38.
  • the latter in its turn lies on the outside of the longitudinal slot 17 there.
  • the corresponding plate is turnable in view of the rotation of the pin 16 or rod 20 itself and in order to secure readiness for engagement is extended over by a fixed slat 18" located above it.
  • a mating toothed slat 40 which can be swung out of the region of its toothed slat 39, cooperates with the jaw 38.
  • the toothed slat is seated on the jaw 41 of an angle lever 43 which is swingable about the fixed pins 42 and the angle arm 44 of which extends horizontally in the basic position is bent slightly downward at its end at 45 and serves as operating handle.
  • Bearing lugs 46 are cut from the horizontal angle arm 44 and bent upward, they being supported by the pivot pins 42 which pass through wings 47 extending from the frame 18.
  • the teeth 48 of the toothed-slat jaw 38 and the teeth 49 of the mating toothed slat 40 of the jaw 41 extend parallel to the slot 17, as in the embodiment which was described by way of example above.
  • This tooth engagement is also under spring action.
  • This spring carries the numeral 50 in the drawing.
  • the seat-base frame 18 rests on a box-shaped carrier 51 and can be moved back and forth in known manner with respect to the carrier.
  • a release handle 52 for a detent tooth 53 which cooperates with a stationary rack 54 of the carrier 51, the rack being guided in the channel 53.
