Abstract
Abstract Vehicle seat safety system in which the occupant or passenger is closely restrained in the seat; the seat back is yieldably restrained in attenuation at a first and lower impact range for forward tilting movement with the occupant; and the seat is yieldably restrained in attenuation at a second and higher range for forward movement of the body and seat as a whole-to first allow the upper portion of the body or torso to move forward under lighter impact loadings, and to allow the body as a whole to move forward under greater impact loadings and thus to minimize, as far as possible, the impact loads on the body and to reduce forward and reverse or snap-back loads on the body torso and neck.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A vehicle seat safety system comprising a seat having a ledge and back, occupant lap and shoulder belt means carried by the seat which closely holds the occupant in the seat, the belt means having an elongation factor of less than 15 percent (15 percent), a yieldable attenuating restraining means for the seat back which yields upon predetermined loading to allow the seat back to tilt forward with the closely confined body torso of the occupant, and a yieldable attenuating restraining means for the seat ledge which yields upon forward impact loading, said yieldable seat back restraining means being yieldable at a lower loading than the yieldable restraining means for the seat ledge.
Claim 2
Dependent Claim
113 words
A vehicle seat safety system comprising a seat having a ledge and back, occupant lap and shoulder belt means carried by the seat which closely holds the occupant in the seat, the belt means having an elongation factor of less than 15 percent (15 percent), a yieldable attenuating restraining means for the seat back which yields upon predetermined loading to allow the seat back to tilt forward with the closely confined body torso of the occupant, and a yieldable attenuating restraining means for the seat ledge which yields upon forward impact loading, said yieldable seat back restraining means being yieldable at a lower loading than the yieldable restraining means for the seat ledge.
Claim 3
Dependent Claim
24 words
A vehicle seat safety system as set forth in claim 1, wherein the belt means has an elongation factor of less than 5 percent.
Claim 4
Dependent Claim
24 words
A vehicle seat safety system as set forth in claim 1, wherein the belt means has an elongation factor of less than 3 percent.
Claim 5
Dependent Claim
38 words
A vehicle seat safety system as set forth in claim 1, wherein shoulder belts are provided for both of the occupant''s shoulders, the shoulder belts being secured at their upper ends to the top of the seat back.
Claim 6
Dependent Claim
29 words
A vehicle seat safety system as set forth in claim 1, wherein the yieldable restraining means for the seat back has increasing resistance to tilting after the yielding stage.
Claim 7
Dependent Claim
45 words
A vehicle seat safety system as set forth in claim 5, wherein said yieldable restraining means for the seat back comprises a corrugation in the back adjacent its lower end which is pulled out when the seat back tilts forward at the top upon impact.
Claim 8
Dependent Claim
29 words
A vehicle seat safety system as set forth in claim 6, wherein the seat back is hinged at the bottom and provided with a latch connection below the corrugation.
Claim 9
Dependent Claim
27 words
A vehicle seat safety system as set forth in claim 1, wherein the yieldable restraint means for the seat ledge imposes increasing restraint as impact loading increases.
Claim 10
Dependent Claim
43 words
A vehicle seat safety system as set forth in claim 1, wherein the yieldable restraining means for the seat back begins to yield at about 10 g., and the yieldable restraining means for the seat ledge begins to yield at about 20 g.
Claim 11
Dependent Claim
24 words
A vehicle seat safety system as set forth in claim 1, wherein the belt means has an elongation factor of less than 3 percent.
Claim 12
Dependent Claim
89 words
A vehicle seat safety system comprising a seat having a ledge and back, occupant lap and shoulder belt means carried by the seat which closely holds the occupant in the seat, the belt means having an elongation factor of less than 15 percent, a yieldable attenuating means for the seat back which yields upon predetermined loading to allow the seat back to tilt forward with the closely confined body torso of the occupant, and a yieldable attenuating restraining means for the seat ledge which yields upon forward impact loading.
Claim 13
Dependent Claim
89 words
A vehicle seat safety system comprising a seat having a ledge and back, occupant lap and shoulder belt means carried by the seat which closely holds the occupant in the seat, the belt means having an elongation factor of less than 15 percent, a yieldable attenuating means for the seat back which yields upon predetermined loading to allow the seat back to tilt forward with the closely confined body torso of the occupant, and a yieldable attenuating restraining means for the seat ledge which yields upon forward impact loading.
Claim 14
Dependent Claim
44 words
A vehicle seat safety system as set forth in claim 11, wherein the yieldable restraint means for the seat ledge is located intermediate the length of the seat, and track and slide support means for the seat located at the ends of the seat.
