Abstract

An electric switch, for incorporation in a seat which includes an elastically extensible web on which a weight on the seat is supported, includes contacts on the web engageable with contacts on a relatively fixed part of the seat, whereby stretching of the web by a weight on the seat operates the switch.

Claims

1. A combined weight-supporting elastically deformable web and electric switch for incorporation into the structure of a vehicle seat, said electric switch comprising a first contact secured to the web at a first position and a second contact engageable by the first contact and mounted on the web at a second position remote from said first position whereby application of a weight to a seat in which the web is incorporated effects extension of that portion of the web between said first and second positions to operate the switch.

2. The combined web and switch claimed in claim 1 further comprising an insulating sleeve surrounding said extensible web, said second contact being mounted on said sleeve at one end and said sleeve being connected to the web at its other end

3. The combined web and switch claimed in claim 2 in which second contact comprises a plurality of contact elements selectively interconnectible by Said first contact.

4. The combined web and switch claimed in claim 3 which comprises a plurality of first contacts and a plurality of associated sets of contact elements the elements in a set being selectively interconnectible by a corresponding one of said first contacts.

5. The combined web and switch claimed in claim 2 which includes a plurality of second contacts, said first contact being operable to interconnect said second contacts.

6. The combined web and switch claimed in claim 3 in which said first contact is resiliently deformable.

7. The combined web and switch claimed in claim 2 further comprising leads for said second contacts said leads being embedded in said sleeve.

8. The combined web and switch claimed in claim 2 in which said sleeve is adapted to be secured to a frame part of the seat.

9. The combined web and switch claimed in claim 2 which said sleeve is secured to said web adjacent one end thereof.

10. The combined web and switch claimed in claim 9 in which said second contact is resiliently deformable.

11. The combined web and switch claimed in claim 9 further comprising a barbed buckle for securing the web to frame members of the seat through which buckle the web is passed permitting the web to be tightened, whereby the relative positions of the first and second contacts may be adjusted.

12. The combined web and switch claimed in claim 9 in which the relative positions of said sleeve and said one end of the web are adjustable

13. The combined web and switch claimed in claim 9 in which the position of said second contact on said sleeve is adjustable.
