Abstract
A back support assembly including a bulb pump which when pumped or squeezed by the user inflates an air cushion to exert the desired pressure and fit against the user's lower back. The cushion is secured to the middle of the elastic belt, which is adapted to wrap around the user's back to position the air cushion against the middle of the user's back. Opposing adjustment straps are attached to the back of the strap. With the belt secured around the user the adjustment straps can be pulled and releasably secured to the belt and/or each other at respective positions exerting the desired force on the air cushion and against the user's back. The bulb pump is conveniently attached to and carried by one of the adjustment straps. It is secured to the rear of that strap, and has its rounded forward portion extending out through an opening in the strap, operatively accessible for inflation/deflation by the user. That is, with this mounting arrangement the bulb pump is out of the way, but still readily accessible for squeeze pumping action by the user, and by its shape, construction and location advantageously has a low profile.
