Abstract
Abstract Deceleration apparatus for a seat in a vehicle mounted for rocking movement in a truss. Linkages associated with the truss operate to constrain the seat to movement along substantially independent orthogonal axes. Energy absorbing devices connected to the vehicle, the rocker yoke, and truss linkages decelerate movement of the seat and its occupant along the independent axes in the event of a crash of the vehicle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
213 words
Crash attenuation apparatus for mounting a seat to the floor of a vehicle and for maintaining said seat substantially parallel to said floor when said seat is subjected to vertical, longitudinal or lateral forces, vertical, longitudinal and lateral energy absorbing devices associated with said seat to absorb energy when said seat is subjected to any of said vertical, longitudinal or lateral forces, rocker yoke means to maintain said seat parallel to said floor when said seat is subjected to said vertical forces, said rocker means including a forward end pivotally attached to said seat and a rear end pivotally mounted to said vertical energy absorbing device, truss means including forward and rear links attached thereto to maintain said seat substantially parallel to said floor when said seat is subjected to longitudinal forces, said truss means being pivotally mounted to said rocker yoke means with said longitudinal energy absorbing device being connected between said floor and said truss means, said forward and rear links being of predetermined lengths with respect to each other to maintain said seat substantially parallel to said floor when said seat is subjected to said longitudinal forces, said forward links further providing means for maintaining said seat substantially parallel to said floor when said seat is subjected to lateral forces.
Claim 2
Dependent Claim
213 words
Crash attenuation apparatus for mounting a seat to the floor of a vehicle and for maintaining said seat substantially parallel to said floor when said seat is subjected to vertical, longitudinal or lateral forces, vertical, longitudinal and lateral energy absorbing devices associated with said seat to absorb energy when said seat is subjected to any of said vertical, longitudinal or lateral forces, rocker yoke means to maintain said seat parallel to said floor when said seat is subjected to said vertical forces, said rocker means including a forward end pivotally attached to said seat and a rear end pivotally mounted to said vertical energy absorbing device, truss means including forward and rear links attached thereto to maintain said seat substantially parallel to said floor when said seat is subjected to longitudinal forces, said truss means being pivotally mounted to said rocker yoke means with said longitudinal energy absorbing device being connected between said floor and said truss means, said forward and rear links being of predetermined lengths with respect to each other to maintain said seat substantially parallel to said floor when said seat is subjected to said longitudinal forces, said forward links further providing means for maintaining said seat substantially parallel to said floor when said seat is subjected to lateral forces.
Claim 3
Dependent Claim
24 words
The invention as set forth in claim 1 wherein said vertical energy absorbing dEvice is connected between said rocker yoke means and said truss.
Claim 4
Dependent Claim
26 words
The invention as set forth in claim 2 wherein said lateral energy absorbing devices are connected between the tops of said forward links and said floor.
