Abstract
Abstract An impact braking device adapted for use with the standard braking systems provided in motor vehicles, the device comprising a slidable bumper operably attached to the vehicle frame structure by an actuator means, wherein at least one actuator is provided with a releasable locking lug. A brake cable is releasably attached to the standard vehicle brake pedal at one end thereof, the other end being secured to a spring-biased locking lever which is held in a locked position by said locking lug. When the bumper is moved inwardly, the locking lug releases the locking lever and allows it to rotate under spring tension, thus causing the brake cable to apply sufficient force to operate the foot brake pedal of the vehicle braking system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
An automatic impact braking device, for use in combination with a motor vehicle brake system, having a foot brake pedal, the automatic impact braking device comprising: an actuator means secured to said vehicle, wherein said actuator means comprises a pair of oppositely disposed actuators having an actuator arm extending forwardly and rearwardly of said actuator; an impact-receiving means secured to one end of said actuator means, wherein said impact-receiving means comprises an impact bumper, said bumper being extended forwardly of said vehicle; a restraining means operably mounted to the opposite end of said actuator means, wherein said restraining means comprises: a removable restraining lug pivotally mounted to said rearward portion of said actuator bar; and a spring-biasing means attached to said lug, whereby said lug is held in a vertical restraining model; a locking means adapted to be releasably held by said restraining means and operably mounted to said vehicle; a pivoting means attached to said locking means whereby said locking means is allowed to pivot when disengaged from said restraining means; and a connecting means secured at one end to said locking means, the opposite end thereof being mounted to said foot-brake pedal of said vehicle.
Claim 2
Dependent Claim
197 words
An automatic impact braking device, for use in combination with a motor vehicle brake system, having a foot brake pedal, the automatic impact braking device comprising: an actuator means secured to said vehicle, wherein said actuator means comprises a pair of oppositely disposed actuators having an actuator arm extending forwardly and rearwardly of said actuator; an impact-receiving means secured to one end of said actuator means, wherein said impact-receiving means comprises an impact bumper, said bumper being extended forwardly of said vehicle; a restraining means operably mounted to the opposite end of said actuator means, wherein said restraining means comprises: a removable restraining lug pivotally mounted to said rearward portion of said actuator bar; and a spring-biasing means attached to said lug, whereby said lug is held in a vertical restraining model; a locking means adapted to be releasably held by said restraining means and operably mounted to said vehicle; a pivoting means attached to said locking means whereby said locking means is allowed to pivot when disengaged from said restraining means; and a connecting means secured at one end to said locking means, the opposite end thereof being mounted to said foot-brake pedal of said vehicle.
Claim 3
Dependent Claim
66 words
An automatic impact braking device as recited in claim 1, wherein said locking means comprises; a locking-lever arm having an enlarged circular ring integrally formed thereon; a pivoting means whereby said lever arm is rotatably secured to said vehicle adjacent the restraining lug for direct engagement therewith; and biasing means attached to said lever arm for imparting rotational movement thereto when disengaged with said restraining lug.
Claim 4
Dependent Claim
