First Claim
Patent Images
1. A seat for a motor vehicle, the seat comprising:
- an occupant detector for recognizing an occupancy status of the seat; and
a foamed cushion element comprising a foam layer, said foam layer includes a plurality of elastically deformable spacing elements, each elastically deformable spacing elements defining a plurality of recesses, the occupant detector being foamed into the cushion element, said occupant detector having at least two electrically conductive contact elements, one of said electrically conductive contact elements being located at a spaced location from another of said electrically conductive contact elements via one or more of said elastically deformable spacing elements, each of said elastically deformable spacing elements engaging each of said electrically conductive contact elements, each of said elastically deformable spacing elements being an electrically insulated foam element.

12. A seat for a motor vehicle, the seat comprising:
-
a seat part with a foamed cushion element; a plurality of elastically deformable spacing elements, each elastically deformable spacing element and another elastically deformable element defining a recess; and an occupant detector for recognizing the occupancy status of the seat, the occupant detector being incorporated into the cushion element by being foamed therein during formation of said foamed cushion element, said occupant detector including a first electrically conductive contact element and a second electrically conductive contact element, said second electrically conductive contact element having one or more projecting portions extending into one or more of said recesses, each of said elastically deformable spacing elements engaging said first electrically conductive contact element and said second electrically conductive contact element, said occupant detector being mounted for movement such that said first electrically conductive contact element is movable from a first position to a second position, said first electrically conductive contact element being located at a spaced location from said second electrically conductive contact element via at least one of said elastically deformable spacing elements when said first electrically conductive contact element is in said first position, at least one of said projecting portions engaging said first electrically conductive contact element in at least one of said recesses when said first electrically conductive contact element is in said second position. - View Dependent Claims (13, 14, 15, 16, 17)

18. A seat for a motor vehicle, the seat being formed by the steps comprising:
-
providing an occupant detector for recognizing the occupancy status of the seat, said occupant detector comprising a first elastically deformable spacing element, a second elastically deformable spacing element, a first electrically conductive contact element and a second electrically conductive contact element, said first elastically deformable spacing element and said second elastically deformable spacing element defining a first space, said second electrically conductive contact element having a first projecting portion, said first projecting portion extending into said first recess, said first electrically conductive element being mounted for movement such that said first electrically conductive element moves from a non-contact position to a contact position, said second first projecting portion being in contact with said first electrically conductive element in said first recess when said first electrically conductive element is in said second position, said first electrically conductive element being located at a spaced location from said second electrically conductive element via one or more of said first elastically deformable spacing element and said second elastically deformable spacing element; placing the occupant detector in a seat region; and forming a cushion element foaming in the occupant detector with foam material as the occupant detector is positioned in the seat region such that the occupant detector is incorporated into a cushion element by being foamed therein during formation of said foamed cushion element. - View Dependent Claims (19, 20)
