Abstract: A test fixture for a testing a vehicle seat mounting includes a first portion and a second portion separate from the first portion and having a fulcrum supported thereon. An energy absorbing member is attached to the test fixture first portion and extends around a portion of the fulcrum. The energy absorbing member is formed so as to have a first shape when the test fixture first portion and second portion are spaced apart less than a predetermined distance. The test fixture is structured so that movement of the second portion in a direction away from the first portion causes the fulcrum to slide along the energy absorbing member. Sliding of the fulcrum along the energy absorbing member plastically deforms the energy absorbing member into a second shape different from the first shape.

Abstract: A front wheel assist drive for a vehicle having a rear wheel main drive includes a hydraulic fluid pump. The pump is connected to a hydraulic motor. The motor is connected to an output shaft. An overrunning clutch is interposed between the motor and output shaft for selectively connecting the shaft to the motor when the motor is turning in a first direction. An output shaft is connected to a front wheel for driving the wheel in a first direction via the motor. A control is connected to the motor for preventing the motor from dynamically braking the vehicle when the wheel is driven in a reverse direction through the main drive.
