A valve is provided at the exit of a bladder (9, figures 1a-c) situated in a car seat (1, figures 1a-c) which can be inflated to adjust the support given by the seat. The valve opens when the ambient temperature inside the car reaches a predetermined level so as to deflate the bladder and prevent the foam of the seat to permanently set in a compressed shape (13, figure 1c). The valve 20 comprises a dished bimetallic actuator 32 which snaps between cold state and hot state conditions. |
