Abstract

A vehicle seat (1) includes a backrest (10) and a table unit (40) which is pivotable about a pivot axis (S) from a not-in-use position into a use position. The backrest (10) includes a backrest cover (20), to which the table unit (40) is fastened. A prestressed table spring (34) is provided. The table unit (40) is held on the backrest (10) by a spring force applied by the table spring (34). The table spring (34) is arranged on a side of the backrest cover (20) which faces away from the table unit (40).

Claims

1. A vehicle seat comprising:

a backrest comprising a backrest faceplate;

a table unit pivotable about a pivot axis from a non-usage position into a usage position, the table unit being fastened to the backrest faceplate;

two rotary journals connected rotationally to the table unit;

two table spring sleeves, each provided with one pin-like projection, which is in alignment with the pivot axis; and

a table spring under preload, wherein;

the table unit is held on the backrest by a spring force imparted by the table spring;

the table spring is arranged on a side of the backrest faceplate which faces away from the table unit;

the projections project into a respective rotary journal opening;

the table spring forces the table spring sleeves in a direction of the rotary journals; and

the table spring sleeves are connected rotationally to the table spring and to the backrest faceplate.

2. A vehicle seat as claimed in claim 1, wherein the table unit locks in the usage position under the action of spring force imparted by the table spring.

3. A vehicle seat as claimed in claim 1, wherein the table unit locks in the non-usage position under the action of spring force imparted by the table spring.

4. A vehicle seat as claimed in claim 1, wherein the central axes of the rotary journals are in alignment with the pivot axis.

5. A vehicle seat as claimed in claim 1, wherein the backrest faceplate has a cylindrical protuberance.

6. A vehicle seat as claimed in claim 5, wherein the rotary journals are situated partially within the protuberance and project into the table unit.

7. A vehicle seat as claimed in claim 5, wherein a cylinder axis of the protuberance is in alignment with the pivot axis.

8. A vehicle seat as claimed in claim 1, wherein:

the table spring is bent approximately in a U-shape and has a central leg and two side legs with spring ends additionally bent outward; and

the spring ends engage into engagement openings of the table spring sleeves.

9. A vehicle seat as claimed in claim 1, wherein the backrest faceplate is composed of plastic.

10. A vehicle seat as claimed in claim 1, wherein the table unit comprises:

a table faceplate; and

a table panel joined together with the table faceplate in a positively locking fashion.

11. A vehicle seat as claimed in claim 1, wherein:

a locking button is attached to the backrest faceplate;

the locking button holds the table unit on the backrest faceplate when the table unit is in the non-usage position.
