Abstract
Abstract The stretcher carrier is supported in an ambulance for tilting about a horizontal axis between a substantially horizontal position and a position inclined to the horizontal. Resilient means are provided to permit oscillation of the tilting axis in substantial vertical direction. The arrangement may also include locking means movable to an operative position to prevent in this position such oscillations.
