Abstract
Abstract An apparatus which supports the body of one working over the engine compartment of an automobile, without otherwise impairing freedom of movement and without relying on any part of the automobile for support, comprising a tubular base and extended frame, pivotally connected to one another, with means for locking the extended frame into an obliquely elevated position with respect to the base. The apparatus stably flexes under load, providing comfortable support in general and relieving back strain in particular. The extended frame and base fold together for convenient storage. In an alternative embodiment, the height of the extended frame is adjustable.
