Abstract
Official abstract text for this publication.
A seat having a seat frame with a seat back designed to prevent injuries to a rear occupant seated behind the seat as the rear occupant moves forward into the seat back during a frontal crash of a vehicle, the seat including a seat back frame part designed to support the back of any occupant but which can rotate during a crash as a rear occupant moves forward into the seat back, the invention including at least one energy absorbing assembly to control the rotary motion of the rotating seat frame part, the rotating frame part maintained in a non-rotating state by an articulating or breakable pin which when moved or broken permits the frame part to rotate as the rear occupant engages the seat frame in response to a frontal vehicular crash.
First claim
Opening claim text (preview).
The invention claimed is: 1. A seat having a seat frame with a seat back designed to prevent injuries to a rear occupant seated behind the seat as the rear occupant moves forward into the seat back during a frontal crash of a vehicle, the seat including a seat back frame part designed to support the back of any occupant but which can rotate during a crash as a rear occupant moves forward into the seat back, the invention including at least one energy absorbing assembly to control the rotary motion of the rotating seat frame part, the rotating frame part maintained in a non-rotating state by an axially articulating pin or breakable pin, the axially articulating pin or breakable pin having a longitudinal axis, wherein moving the axially articulating pin along the longitudinal axis or breaking the breakable pin permits the frame part to rotate as the rear occupant engages the seat frame in response to a frontal vehicular crash. 2. The seat according to claim 1 wherein the at least one energy absorbing assembly includes a first energy absorbing mechanism, wherein the first energy absorbing mechanism is a torsion bar. 3. The seat according to claim 2 wherein the at least one energy absorbing assembly includes a second energy absorbing mechanism, wherein the second energy absorbing mechanism assists the torsion bar.
