Vehicle seat with shock absorption

A vehicle seat comprising:

• a seat base;
• track means coacting with said seat base for adjustably supporting the seat within the vehicle;
• means for mounting at least one first shock absorber between said seat base and said track means;
• a seat back;
• means on said seat base for pivotally supporting said seat back;
• at least one second shock absorber connected in coacting relation between said seat back and said seat base;
• and
• shear means affixing said seat base to said track means for providing upon shearing shock absorbed movement between said seat base and said track means.

A vehicle seat comprising:

• a seat base;
• track means coacting with said seat base for adjustably supporting the seat within the vehicle;
• means for mounting at least one first shock absorber between said seat base and said track means;
• a seat back;
• means on said seat base for pivotally supporting said seat back;
• at least one second shock absorber connected in coacting relation between said seat back and said seat base;
• and
• wherein said mounting means includes at least one shear pin affixing said seat base to said track means whereby, on impact with the rear of the vehicle, the shear pin shears thereby enabling relative movement between said seat base and said track means under damped control of said at least one first shock absorber.

A vehicle seat comprising:

• a seat base;
• track means coacting with said seat base for adjustably supporting the seat within the vehicle;
• means for mounting at least one first shock absorber between said seat base and said track means;
• a seat back;
• means on said seat base for pivotally supporting said seat back;
• at least one second shock absorber connected in coacting relation between said seat back and said seat base;
• and
• wherein said supporting means includes a shearable member for permitting rearward movement of said seat back relative to said seat base on shearing thereof under force of an impact with the rear of the vehicle thereby enabling rearward movement of said seat back relative to said seat base under damped control of said at least one second shock absorber.

A vehicle seat comprising:

• a seat base;
• track means coacting with said seat base for movably supporting the seat within the vehicle;
• means for mounting at least one first shock absorber between said seat base and said track means, said mounting means;
• including at least one first shear member for normally fixing the position of said seat base relative to said track means;
• a seat back;
• means on said seat base for pivotally supporting said seat back;
• and
• means for attachment of at least one second shock absorber in coacting relation between said seat back and said seat base, said attachment means including at least one second shear member for normally preventing rearward movement of said seat back relative to said seat base, whereby, under force of a rear impact on the vehicle, said at least one first and second shear members shear enabling rearward movement of said seat back relative to said seat base under damped control of said at least one second shock absorber and enabling rearward movement of said seat base relative to said track means under damped control of said at least one first shock absorber.

A vehicle seat having a seat base mounted on a track for movably supporting the seat to the floor of said vehicle, and a seat back, the seat including an energy absorbing damping system and a seat back frame arrangement for height and contour adjustment for an occupant, said seat comprising:

• first damping means in coacting relationship between said seat base and said track for absorbing impact energy between said seat base and the floor of said vehicle upon impact of the vehicle;
• second damping means in coacting relationship between said seat base and said seat back for absorbing impact energy between said seat base and said seat back upon impact of the vehicle;
• telescoping seat means for adjustment for the height of the occupant;
• seat back construction including individually configurable and positionable components for the lower back, the middle back, and the head/neck area, each relative to the other, for adjusting the contour of the back of said seat to the back of the occupant.
