An occupant weight sensing apparatus configured to be coupled to a vehicle seat. The apparatus includes a base configured to be connected to a vehicle, a lever pivotally connected to the base, a rocker configured to be connected to the vehicle seat, the rocker also pivotally connected to the lever, and a sensor coupled to the lever. A force applied to the seat causes pivotal movement of the lever relative to the base. The sensor detects the pivotal movement to sense the weight of the occupant.

Occupant weight sensing using intelligent fastener and vertical load transmitting brackets

Automotive load cells having centralized, multi-axis, loose tolerance overload/limit stops provide improved strain gauge response. The modular, integrated stop assemblies magnify sensor substrate deflection by use of opposed concave (Belleville) springs are used in direct contact with the substrate to accommodate &#xb1;Z axis deflection and Mx/My moment angular rotation. A flanged guide member on the load stud permits a wide range of geometries. The substrate is thickened around the load stud hole and the outboard support bolt holes. Hollow rivets assist in design modularity. Strain gauges are placed at the yield zones symmetrically with respect to the X axis. The substrate hole Mx/My gap is larger than the stop bracket hole to insure a positive stop for Mx/My moments prior to yield. The inventive multi-axis stop assembly is used in any type load cell, including rectangular, thinned, notched, necked/dogbone, or cantilever substrates with any strain gauge layout configuration.

Weight sensors having centralized loose tolerance universal force and Mx/My moments overload stops

An apparatus and method for supporting a load-bearing platform (e.g., a seat) and measuring the weight of a load (e.g., an occupant) on the platform. The apparatus can include a base or support, a lever coupled to the support, and a sensor. The lever can be pivotally coupled to the support to allow pivotal movement of the lever with respect to the support in response to weight applied to the platform. The sensor can detect the force transmitted by the lever to determine the weight of the load on the platform. Furthermore, the lever can isolate the vertical load on the platform due to the weight of the load from other extraneous, non-vertical forces on the platform.
