Abstract: An apparatus which enables a person to comfortable work on the engine of a vehicle includes base, spine, post, knee pad, and chest pad components. The spine component is pivotally connected to the base component. A brace prevents the pivoting movement but is removably connected between the spine and the base to allow pivoting when desired. The spine component carries the tube component at a selected height, and the tube component carries the knee pad component at a selected position. The tube component carries the chest pad component.

Abstract: A device (10) which assists a person (P) in working on the engine (E) of a vehicle (V) includes a base member (11) which rests on the ground and has a socket (17) extending upwardly therefrom. A post assembly (23) includes a stem portion (24) which is selectively positionable within the socket (17). The stem portion (24) is provided with a plurality of opposed spaced apertures (27), and a pin (28) is inserted through a selected of the opposed apertures (27) and through apertures in the socket (17) to adjust the height of the device (10). A step (29) is carried by the stem portion (24) at a selected height by a pin (31) received through the selected apertures (27) and through apertures in a flange (30) carried by the step (29).
