ABSTRACT:
A seat for a public transport vehicle has a handle for use by people who are standing rather than sitting in the vehicle. The handle is mounted in pivot bearings, but is normally restrained from pivoting by a shear pin. In a crash, a seated person may be jerked forward so that his head hits the handle. If this happens, the shear pin breaks so that the handle can pivot forward and does not present an obstacle which could damage the person's head.
