Abstract
The invention relates to a motor vehicle seat (1) having a seat cushion frame (3) which has seat cushion frame side members (5) and is supported by a four-element linkage with front and rear coupling linkages (9) at a height H relative to a floor, and with a backrest frame (4) which has backrest frame side members (6). A change in the height H of the seat cushion frame (3) is possible via a seat height adjustment device. By means of a backrest inclination adjustment device (17), a change in the inclination of the backrest frame (4) can be effected. A connecting tube (25) connects the two seat cushion frame side members (5) to one another. The connecting tube (25) is also connected to the rear coupling linkages (9). The adjustment axis runs through the cross-section of the connecting tube (25).
Claims18
A motor vehicle seat comprising
- a) a seat cushion frame that has seat cushion frame side members and is supported at a height H relative to a floor by means of a four-element linkage with front and rear coupling linkages,
- b) a back rest frame which has backrest frame side members,
- c) a seat height adjustment device for changing the height H of the seat cushion frame,
- d) a backrest inclination adjustment device for changing the inclination of the backrest frame in relation to the seat cushion frame about an adjustment axis, and
- e) a connecting tube which connects the two seat cushion frame side members to one another and is connected to the rear coupling linkages
- wherein
- f) the adjustment axis runs through the cross-section of the connecting tube, and wherein the adjustment axis extends with an offset through the connecting tube.
A motor vehicle seat comprising:
- a) a seat cushion frame that has seat cushion frame side members and is supported at a height H relative to a floor by means of a four-element linkage with front and rear coupling linkages,
- b) a back rest frame which has backrest frame side members,
- c) a seat height adjustment device for changing the height H of the seat cushion frame,
- d) a backrest inclination adjustment device for changing the inclination of the backrest frame in relation to the seat cushion frame about an adjustment axis, wherein the backrest inclination adjustment device has a right-hand backrest inclination adjustment unit and a left-hand backrest inclination adjustment unit which are coupled to one another via a coupling rod, and
- e) a connecting tube which connects the two seat cushion frame side members to one another and is connected to the rear coupling linkages,
- wherein
- f) the adjustment axis and the coupling rod run through the cross-section of the connecting tube, and wherein the coupling rod extends with an offset through the connecting tube.
A motor vehicle seat comprising:
- a) a seat cushion frame that has seat cushion frame side members and is supported at a height H relative to a floor by means of a four-element linkage with front and rear coupling linkages, the seat cushion frame side members being Y-shaped or forked, with a base leg and two fork legs, wherein each of the fork legs comprises a bearing lug and wherein a bearing lug axis of the bearing lugs of the fork legs are arranged with an offset relative to one another,
- b) a back rest frame which has backrest frame side members,
- c) a seat height adjustment device for changing the height H of the seat cushion frame,
- d) a backrest inclination adjustment device for changing the inclination of the backrest frame in relation to the seat cushion frame about an adjustment axis, and
- e) a connecting tube which connects the two seat cushion frame side members to one another and is connected to the rear coupling linkages
- wherein
- f) the adjustment axis runs through the cross-section of the connecting tube.
