Definitions

  • the invention relates to a vehicle seat, in particular a motor vehicle seat, with the features of the preamble of claim 1.
  • a seat pan In a vehicle seat of this type, a seat pan is pivotally mounted on the front on a cross tube of a seat frame and resiliently on the rear of the seat frame. If the occupant is loaded, the seat pan swings slightly around the cross tube.
  • a rigid mounting bracket is provided as the bearing device, which surrounds the cross tube from below and is fastened to the seat shell with clips. From above, the seat shell rests on the cross tube via a counter bearing. This training leaves nothing to be desired.
  • the invention is based on the object of improving a vehicle seat of the type mentioned. This object is achieved by a vehicle seat with the features of claim 1. Advantageous refinements are the subject of the dependent claims.
  • the fastening element is elastic, it can rest against at least one of the parts to be stored without play.
  • the fastening element is preferably also mounted in the bearing device under pretension, in order to simultaneously compensate for tolerances and to be rattle-free when driving, ie to prevent disturbing noises in the bearing device.
  • the command Stistselement is preferably designed as a spring clip, other spring element or other elastic element.
  • the design according to the invention is particularly advantageous if the fastening element at least partially surrounds the first component of the bearing device forming the axis for a pivoting movement in the circumferential direction and is fastened to the pivotable second component.
  • the fastener is direct, i.e. without screwing or clips or other additional fastening elements, attached to the swiveling second component.
  • a bearing shell provided for reducing the friction preferably made of a different material than the components which can be pivoted relative to one another, can be arranged between the fastening element and / or the pivotable second component on the one hand and the first component forming the axis for the pivoting movement on the other hand in its radial direction and almost completely enclose the first component.
  • the bearing shell can be constructed in several parts or in one part. Such a bearing shell can be attached to the fastener.
  • FIG. 3 shows a vertical section through the storage device according to the invention along the line III-III in FIG. 1, 4 shows a representation of the spring clip according to the invention and the bearing shell corresponding to FIG. 3, but in the untensioned state before assembly,
  • Fig. 5 is an illustration corresponding to FIG. 3 for the second embodiment
  • Fig. 6 is an illustration corresponding to FIG. 3 for the third embodiment.
  • a vehicle seat 1 for a motor vehicle has in its seat part a seat frame 3 which carries a seat cushion 5 in the manner described below.
  • the directional information used relates to the usual arrangement of the driving
  • Tool seat 1 in the motor vehicle and its usual direction of travel (x direction).
  • the seat frame 3 In its front area, the seat frame 3 has a hollow cylindrical cross tube 7, running horizontally and transversely to the direction of travel (i.e. in the y direction), as a first component, on which the front area of the seat shell 9 as a second
  • Component is attached, which in turn carries the seat cushion 5. To connect the
  • Bearing device 11 is provided, by means of which the seat shell 9 can be pivoted relative to the cross tube 7 at least over a certain angular range, for example if the rear region of the seat shell 9 is spring-mounted and is pivoted by an occupant.
  • each bearing device 11 comprises an approximately semi-cylindrical, short plastic bearing shell 13 which surrounds the cross tube 7 in the circumferential direction thereof almost over half and extends in the axial direction of the cross tube 7 and which bears on the underside of the cross tube 7.
  • the radius of curvature of the inside of the bearing shell 13 corresponds approximately to that of the outside of the cross tube 7.
  • the bearing shell 13 lies on the opposite Top of the cross tube 7 on an approximately also semi-cylindrical counter bearing 15, which has the same radius of curvature on the inside, but a slightly larger length in the y direction.
  • the counter bearing 15 is located in a semi-cylindrically curved receptacle on the underside of the seat shell 9 and is fastened to it by a clip connection.
  • the counter bearing 15 is thus arranged between the seat shell 9 and the cross tube 7 in its radial direction.
  • the bearing device 11 has as a fastening element transverse to the direction of movement between the seat shell 9 and the cross tube 7 a spring clip 21 which holds the bearing shell 13 in contact with the cross tube 7, i.e. with respect to the cross tube 7 in its radial direction.
  • the one-piece, mirror-symmetrical spring clip 21, which is designed in the manner of a leaf spring made of spring steel, has a central section 23 and a side section 25 adjoining it laterally (in the x-direction in front and behind). In the assembled, tensioned state of the spring clip 21, the middle section 23 lies against the outside of the bearing shell 13 pointing downward (i.e. against the z direction) and, in an untensioned state, has a slightly larger radius of curvature than this outside of the bearing shell 13 before assembly.
  • Each side section 25 is curved upward from the central section 23 and ends in an inwardly curved hook 27.
  • the side section 25 is pushed from below with its hook 27 through an opening 29 in the x-direction in front of or behind the cross tube 7 in the seat shell 9, the spring clip 21 first being slightly bent, ie tensioned, until the Hook 27 is completely pushed through and engages behind the seat shell 9 in the edge region of the opening 29.
  • the spring clip 21 relaxes slightly, but remains biased.
  • the seat shell 9 can now rotate relative to the cross tube 7, for example in the case of the aforementioned load by an occupant.
  • the bearing shell 13 and the counter bearing 15 are equal to tolerances so held in abutment on the cross tube 7 that the seat shell 9 is not mounted too stiffly, but also no disturbing rattling noises occur.
  • a second exemplary embodiment largely coincides with the first exemplary embodiment, so that the same and equivalent parts have reference numerals 100 higher.
  • the bearing device 111 between the cross tube 107 and the seat shell 109 has the same spring clip 121, but the bearing shell 113 and the counter bearing 115 are designed as a common plastic injection molded part and are connected to one another by a thin film hinge 117.
  • the bearing shell 113 is thereby pre-positioned in the radial direction until the spring clip 121 is attached.
  • a third exemplary embodiment also largely corresponds to the first exemplary embodiment, so that the same and equivalent parts have reference numbers 200 higher.
  • the bearing device 211 between the cross tube 207 and the seat shell 209 has the same counter bearing 215, but the bearing shell 213 is fastened to the otherwise unchanged spring clip 221 by a clip connection 219. The bearing shell is also brought into a predefined position before assembly.
