A weight sensor (10) senses a load applied to a vehicle seat (12). The sensor includes a first mounting member (40; 120) and a second mounting member (42; 122) positioned opposite from and movable relative to the first mounting member (40; 120). A pair of spaced apart and opposed guide elements (44 and 46; 132 and 134) are connected between the first and second mounting members (40 and 42; 120 and 122), respectively. The pair of guide elements (44 and 46; 132 and 134) guide relative movement between the first and second mounting members (40 and 42; 120 and 122). Biasing means (44 and 46; 132 and 134) are provided for urging a spaced apart relationship between the first and second mounting members (40 and 42; 120 and 122). A variable reluctance sensor (90; 150) is operatively positioned between the first and second mounting members (40 and 42; 120 and 122) and has a variable reluctance condition responsive to the relative spacing between the first and second mounting members (40 and 42; 120 and 122) and indicative of the applied load in the seat.
