a vehicle seat 1 for a motor vehicle has in its seat part a seat frame 3 which supports a seat cushion 5 in the manner described below . the directional details used refer to the customary arrangement of the vehicle seat 1 in the motor vehicle and its customary direction of travel ( x - direction ). in its front region , the seat frame 3 has , as a first component , a hollow cylindrical transverse tube 7 which runs horizontally and transversely to the direction of travel ( i . e . in the y - direction ) and to which the front region of the seat shell 9 is fastened , as a second component . the seat shell 9 in turn supports the seat cushion 5 . in order to connect the seat shell 9 to the transverse tube 7 , a bearing device 11 is provided on both end sections of the transverse tube 7 . the bearing device 11 can be used to pivot the seat shell 9 at least over a certain angular region relative to the transverse tube 7 if , for example , the rear region of the seat shell 9 is mounted resiliently and is pivoted by an occupant . in the first exemplary embodiment , each bearing device 11 comprises an approximately semicylindrical , short plastic bearing shell 13 which extends virtually half way around the transverse tube 7 in the circumferential direction thereof , runs in the axial direction of the transverse tube 7 and bears against the transverse tube 7 on the lower side thereof . the radius of curvature of the inner side of the bearing shell 13 approximately corresponds to that of the outer side of the transverse tube 7 . lying opposite the bearing shell 13 on the upper side of the transverse tube 7 is an approximately likewise semicylindrical counterbearing 15 which has the same radius of curvature of the inner side , but a somewhat longer length in the y - direction . the counterbearing 15 lies in a semicylindrically curved socket on the lower side of the seat shell 9 and is fastened to the latter by means of a clip connection . the counterbearing 15 is thus arranged between the seat shell 9 and the transverse tube 7 , in the radial direction of the transverse tube . as a fastening element extending transversely to the direction of movement , the bearing device 11 has a spring clamp 21 between the seat shell 9 and transverse tube 7 . the spring clamp keeps the bearing shell 13 in contact with the transverse tube 7 , i . e . with respect to the transverse tube 7 in the radial direction thereof . the integral , mirror - symmetrical spring clamp 21 , which is formed from spring steel in the manner of a leaf spring , has a central section 23 and a respective side section 25 laterally adjoining the central section ( in front of it and behind it in the x - direction ). in the fitted , stressed state of the spring clamp 21 , the central section 23 rests on the downwardly pointing ( i . e . counter to the z - direction ) outer side of the bearing shell 13 and in an unstressed state before installation has a slightly larger radius of curvature than this outer side of the bearing shell 13 . each side section 25 is curved upward from the central section 23 and merges into an inwardly curved hook 27 . during installation , the side section 25 is pushed from below with its hook 27 through an opening 29 in the seat shell 9 , which opening is situated in front of or behind the transverse tube 7 in the x - direction , the spring clamp 21 first of all being bent upward somewhat , i . e . being stressed , until the hook 27 is pushed through completely and engages behind the seat shell 9 in the edge region of the opening 29 . the spring clamp 217 is relaxed slightly as a result , but remains prestressed . the seat shell 9 can now rotate relative to the transverse tube 7 , for example in the case of the above - mentioned loading by means of an occupant . the bearing shell 13 and the counterbearing 15 are kept in contact with the transverse tube 7 by the spring clamp 21 , with tolerances being compensated for in such a manner that the seat shell 9 is not mounted too stiffly , but also with no annoying rattling noises arising . a second exemplary embodiment largely coincides with the first exemplary embodiment , so that parts which are identical and act in an identical manner bear reference numbers which are incremented by 100 . in the second exemplary embodiment , the bearing device 111 has the same spring clamp 121 between the transverse tube 107 and seat shell 109 , but the bearing shell 113 and the counterbearing 115 are designed as a common injection molded plastic part and are connected to each other by a thin film hinge 117 . as a result , the bearing shell 113 is pre - positioned in the radial direction before the spring clamp 121 is attached . a third exemplary embodiment likewise largely coincides with the first exemplary embodiment , so that parts which are identical and act in an identical manner bear reference numbers incremented by 200 . in the third exemplary embodiment , the bearing device 211 has the same counterbearing 215 between the transverse tube 207 and seat shell 209 , but the bearing shell 213 is fastened to the otherwise unchanged spring clamp 221 by means of a clip connection 219 . the bearing shell is also already brought into a predefined position before installation . modifications are also conceivable , in which a suitable coating of the transverse tube and spring clamp renders the bearing shells and counterbearings unnecessary .
