Abstract: A seat frame-based occupant weight estimation load cell transfers the seat force to a floor bracket through a spherical ball and a ball actuator. The ball is in contact with the force sensor and has minimal contact area with either the ball actuator or the force sensor so that the transfer of forces not functionally related to occupant weight is minimized. The ball actuator is coupled to the seat frame, and a sensor bracket aligns the ball actuator with respect to the sensor. The sensor bracket is domed to securely anchor the seat to the floor bracket in the event of an inverse overload. A spring disposed between the ball actuator and the dome of the sensor bracket biases the ball against the force sensor to preload the force sensor for enabling off-loading detection.

Abstract: A torque sensor comprising a shaft of magnetostrictive material; a pair of magnets having oppositely sensed poles positioned circumferentially around the shaft so as to induce a localized magnetic field in the shaft between the poles. A torque applied to the shaft is sensed by a flux detector positioned circumferentially between the magnet poles so as to detect a component of the localized magnetic field which escapes from the shaft as a result of the torque. With this design, there is no need to permanently magnetize the shaft or a collar attached to the shaft, as in the prior art. The prior art manufacturing step of permanently magnetizing the collar or its shaft is also thus eliminated, greatly simplifying the manufacturing.
