Abstract

A power adjustable vehicle seat with a seating that is adjustable in height has a side part and an electromotor. The electromotor comprises a flange-mounted transmission, which transmission is provided with an output shaft and with a transmission case. The side part is provided with a bearing for the output shaft. The transmission case has an area axially facing said bearing for the output shaft. The area facing the side part is open-ended by having no case wall on that open end axially facing the bearing for the output shaft. The side part functions as a case wall of the transmission case once the transmission case is fastened to the side part.

Claims

1. Power adjustable vehicle seat with seating which is adjustable in height and has a side part and an electromotor, the electromotor having a flange-mounted transmission, which transmission is provided with an output shaft and a transmission case adapted to be fastened to the side part, the side part being provided with a bearing for the output shaft;

said transmission case having a side axially facing said bearing for the output shaft, said side facing the side part being open-ended, where said open-ended side is axially facing the bearing for the output shaft, the side part acting as a cover on the open-ended side of the transmission case once the transmission case is fastened to the side part.

2. Vehicle seat according to claim 1, wherein a pinion is arranged on said output shaft, said pinion has an outside diameter, said bearing of said side part has a clear inside diameter, said clear inside diameter of said bearing in said side part is greater than said outside diameter of said pinion, so that said pinion may be inserted through said bearing of said side part.

3. Vehicle seat according to claim 1, wherein said side part has a bore having a diameter sufficient in size to receive said bearing, said side part being constant in thickness at the diameter of said bore receiving said bearing.

4. Vehicle seat according to claim 1, wherein a first fastening means is provided in said side part adjacent said bearing;

said transmission case further having a second fastening means which second fastening means is provided in said transmission case, said first fastening means and said second fastening means being aligned and cooperating for a fixation of said transmission case onto said side part.

5. Vehicle seat according to claim 4, wherein said first fastening means is designed as bearings and said second fastening means are tap holes.

6. Vehicle seat according to claim 1, wherein said seat side part has a rim area and a main surface inside said rim area, said rim area projecting obliquely from said main surface, and said rim area projecting towards said electromotor.

7. Vehicle seat according to claim 6, wherein said side part has an outer side and said rim area is located above and underneath said electromotor as well as on said outer side of said side part.

8. Vehicle seat according to claim 1, wherein a pinion is connected to said output shaft, said side part is located between said pinion and said electromotor.

9. Vehicle seat according to claim 1, wherein said bearing of said output shaft is made as a separate bearing piece and is connected to said side part.

10. Vehicle seat according to claim 9, wherein said bearing is formed as an integral part of a bearing part, said bearing part a) bearing a transverse shaft and b) being connectable to said side part.

11. Vehicle seat according to claim 1, wherein said bearing is designed as an integral part of said side part.

12. Vehicle seat according to claim 1, wherein said bearing is designed as a separate part of said side part.
