Abstract

Abstract A power source actuating the protective mechanism shielding the occupants of a vehicle involved in collision which is activated, without the need for sensors or switching devices, by the inertial forces released due to the sudden deceleration of the vehicle. The protective mechanism includes a flexible cage restraining means positioned by a pivoted lever driven by the power source. Means are included for increasing the speed of the power source so that the protective mechanism is always driven at a proportionately higher speed than that of the occupant in relation to the speed of the decelerating vehicle.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 161 words
An occupant restraining mechanism for an automotive vehicle having a floor comprising a barrier for restraining forward movement of an occupant of the vehicle and which is mounted on the vehicle for movement between an inactive position and an occupant restraining position, a weight mounted and arranged on the vehicle for inertial movement in a forward direction upon head-on impact of the automotive vehicle with another vehicle, a lever mounted for pivotal movement on said automotive vehicle from an upright position to an inclined position and being connected to the barrier for the movement thereof from its inactive position to its restraining position by said pivotal movement, pivot means establishing a horizontal pivot axis adjacent said floor for said pivotal movement of the lever and which extends transversely of the direction of movement of said automotive vehicle, and transmission means interconnecting the weight and lever for transmitting said inertial forward movement of said weight into said pivotal movement of said lever.
Claim 2
Dependent Claim 161 words
An occupant restraining mechanism for an automotive vehicle having a floor comprising a barrier for restraining forward movement of an occupant of the vehicle and which is mounted on the vehicle for movement between an inactive position and an occupant restraining position, a weight mounted and arranged on the vehicle for inertial movement in a forward direction upon head-on impact of the automotive vehicle with another vehicle, a lever mounted for pivotal movement on said automotive vehicle from an upright position to an inclined position and being connected to the barrier for the movement thereof from its inactive position to its restraining position by said pivotal movement, pivot means establishing a horizontal pivot axis adjacent said floor for said pivotal movement of the lever and which extends transversely of the direction of movement of said automotive vehicle, and transmission means interconnecting the weight and lever for transmitting said inertial forward movement of said weight into said pivotal movement of said lever.
Claim 3
Dependent Claim 30 words
An occupant restraining mechanism as defined in claim 1 wherein said weight is pivotally mounted on said vehicle for inertial pivotal movement in said forward direction upon said head-on impact.
Claim 4
Dependent Claim 29 words
An occupant restraining mechanism as defined in claim 2 wherein said transmission means comprises an arm which is fixed to and pivotally movable with said lever and said weight.
Claim 5
Dependent Claim 32 words
An occupant restraining mechanism as defined in claim 2 wherein said transmission means comprises gear means for transmitting said inertial pivotal movement of said weight into said pivotal movement of said lever.
Claim 6
Dependent Claim 27 words
An occupant restraining mechanism as defined in claim 1 which comprises a latch mounted on said automotive vehicle to releasably engage said lever at said second position.
Claim 7
Dependent Claim 45 words
An occupant restraining mechanism as defined in claim 2 wherein the lever has a pivot end and a free end and the center of gravity of said lever is located between the midpoint between said pivot end and said free end and said pivot means.
Claim 8
Dependent Claim 178 words
An occupant restraining mechanism for an aUtomotive vehicle having a floor comprising a barrier for restraining forward movement of an occupant of the vehicle and which is mounted on the vehicle for movement between an inactive position and an occupant restraining position, a lever mounted for pivotal movement on said automotive vehicle from an upright position to an inclined position pivotally forwardly of said upright position and being connected to the barrier for the movement thereof from its inactive position to its restraining position by said pivotal movement, pivot means establishing a horizontal pivot axis adjacent said floor for said pivotal movement of the lever and which extends transversely of the direction of movement of said automotive vehicle, and said lever having a pivot end and a free end and an inertia weight operatively connected at said pivot end between the midpoint between said pivot end and said free end and said pivot means, whereby said lever is inertially movable from said upright position to said inclined position upon head-on impact of the automotive vehicle with another vehicle.
Claim 9
Dependent Claim 178 words
An occupant restraining mechanism for an aUtomotive vehicle having a floor comprising a barrier for restraining forward movement of an occupant of the vehicle and which is mounted on the vehicle for movement between an inactive position and an occupant restraining position, a lever mounted for pivotal movement on said automotive vehicle from an upright position to an inclined position pivotally forwardly of said upright position and being connected to the barrier for the movement thereof from its inactive position to its restraining position by said pivotal movement, pivot means establishing a horizontal pivot axis adjacent said floor for said pivotal movement of the lever and which extends transversely of the direction of movement of said automotive vehicle, and said lever having a pivot end and a free end and an inertia weight operatively connected at said pivot end between the midpoint between said pivot end and said free end and said pivot means, whereby said lever is inertially movable from said upright position to said inclined position upon head-on impact of the automotive vehicle with another vehicle.
