Abstract
Seat lifting devices disposed between a seat support for supporting a seat cushion and a seat mount for mounting the seat support are taught that comprise a front and rear linking mechanisms movably interconnecting the seat support and the seat mount. These linking mechanisms are arranged and constructed to vertically adjust the seat cushion when operated. The rear linking mechanism comprises a first linking arm that is pivotally connected to the seat mount and the seat support, and a second linking arm that is pivotally connected to the seat support. The second linking arm is provided with a rear slide pin that slidably engages a rear guide slot formed in the seat mount. The rear slide pin is arranged and constructed to engage a plurality of teeth formed in the rear guide slot when a large force is applied to the seat support in a direction to separate the seat support from the seat mount.
