Abstract

The invention relates to a device for receiving a force applied to a seat, particularly a vehicle seat. Said device comprises at least one spring element (5) for elastically positioning the seat in such a way that the seat support components (1,2,3,4) are coupled together by means of the spring element (5). The inventive device also comprises a sensor which detects the spring excursion or an alteration of the spring excursion or a position of the spring element.

Claims

1. Device for detecting a force acting on a seat, specifically a vehicle seat,

having at least one spring element (5) for resilient mounting of the seat in such a way that seat support components (1,2,3,4) are interconnected via the spring element (5), and

having a sensor for detecting the spring deflection or a change in the spring deflection or in a position of the spring element,

characterized in that the spring element (5) at maximum excursion exhibits a spring deflection of equal to or greater than 0.2 mm.

2. Device according to claim 1,

wherein the spring element (5) at maximum excursion exhibits a spring deflection of equal to or greater than 0.5 mm.

3. Device according to one of the preceding claims,

wherein the spring element (5) at maximum excursion exhibits a spring deflection of equal to or greater than 1 mm.

4. Device according to one of the preceding claims,

wherein the spring element (5) contains a steel spring.

5. Device according to one of the preceding claims,

wherein the spring element (5) is disposed in a housing (6).

6. Device according to one of the preceding claims,

wherein a stop (11) is provided which prevents deformation of the spring element (5) beyond a defined extent.

7. Device according to one of the preceding claims,

wherein the spring element (5) is connected to a seat rail (2) in which the seat is displaceably mounted and to a mounting base (1).

8. Device according to claim 7,

wherein each seat rail (2) assigned to the seat is connected to the mounting base (1) via a separate spring element (5).

9. Device according to claim 7 or claim 8,

wherein the seat rail (2) is fixed to the spring element (5), and the housing (6) is fixed to the mounting base (1).

10. Device according to one of the preceding claims,

wherein the spring element (5) is connected to a first component of a seat frame (3) supporting the seat and displaceably mounted in the seat rail (2) and to a second component of said seat frame (3).

11. Device according to one of the preceding claims,

wherein the spring element (5) is connected to a seat frame (3) supporting the seat and displaceably mounted in the seat rail (2) and to a seat cross-brace (4).
