Abstract: A jockey seat assembly is adapted to be used on a motorized vehicle and includes a saddle seat having a substantially inverted U-shaped configuration. A height adjusting mechanism is provided for the seat and has an upper frame mounted beneath the saddle seat, a lower frame adapted to be secured to a bottom surface of the vehicle and a collapsible lever assembly interconnected between the upper and lower frames. A biasing arrangement is secured between outermost ends of the lever assembly in the upper frame and the lower frame for urging the upper frame and the seat away from the lower frame. A pair of adjustment plates are fixed externally to the lever assembly and provided with a series of slots defining a number of vertical height adjusting positions. An actuator extends forwardly of the seat and the upper frame and is pivotally connected to the upper frame. The actuator has a pair of links normally biased into engagement with the slots for normally establishing a desired vertical height adjustment for the seat relative to the lower frame upon pivotal movement of the actuator. The jockey seat assembly may optionally include a pair of adjustable leg supports, a pair of handlebars and a backrest for further support.

Abstract: An emergency conveyance seat includes a frame for supporting a seat cushion and a back cushioning arrangement. The frame includes a pair of spaced apart channels connected by an enclosure adapted to receive a self-contained breathing apparatus. The channels provide attachment structure for mounting the back cushioning arrangement thereon. One of the channels provides a protective housing for an elongated seat belt webbing having one end attached to a retractor positioned within the channel and a second end attached to a lower portion of the frame.
