Force absorbing shoulder belt assemblies for vehicle seats (e.g., aircraft seats) absorb and thereby reduce shoulder belt forces on the upper torso of a seat occupant in the event of a rapid deceleration event (e.g., a vehicle crash). A one-piece base mounting plate is provided which includes a central base plate section, a forwardly bent section and a forwardly projecting section extending from the forwardly bent section subjacent to the central base plate section. A pair of aligned perforations formed through the central base plate section laterally adjacent to the forwardly projecting section may be provided. The exertion of a deceleration force of predetermined magnitude on the shoulder web strap of an inertial reel attached to the forwardly projecting section along a force vector will cause a shear pin bolt normally connecting the central base plate section to the subjacent forwardly projecting section to shear thereby separating the latter from the former which in turn causes the forwardly bent portion to unbend in a direction of the force vector and/or to tear the central base plate section along the aligned perforations thereby absorbing at least a portion of the deceleration force.
