ENHANCED VEHICLE SAFETY BUMPER (EVSB)

PARE-CHOCS DE SECURITE AMELIORE POUR VEHICULE

English Abstract

Most of the dangerous accidents occur during the head on collisions of
vehicles from the front
or the rear. The Bumpers are designed to take impact loading but in most of
the cases the
impact from the bumpers is transmitted to the vehicle body and to the
occupants. To reduce
the impact on the vehicle body and its occupants various designs of bumpers
have been tried
out including special materials and flexing of bumpers. Yet the extent of
damage to the
vehicles and injuries of occupants have not been drastically reduced.
The Enhanced Vehicle Safety Bumper (referred to as ESVB, in short) consists of
a double
walled Bumper design with compression springs in between. The design, rating,
size,
selection and number of compression springs is such that the entire impact
load transmitted
during a collision would be absorbed by the compression springs via the outer
bumper wall.
The outer bumper wall would be the first to face the impact load and it would
transfer the
same to the compression springs. The compression springs are designed to
absorb two
opposite forces (both the vehicles in the accident) and would compress and
deflect under load
such that there would be none or minimal load transmission of impact to the
inner bumper
wall which is attached to the vehicle frame. Thus the collision load/impact is
not transmitted
to the vehicle body and hence the occupants of the vehicle
The above design would cause minimal damage to the vehicle as well as to its
occupants
during any accident or collision saving immense cost due to vehicle damage or
injuries to the
occupants of the vehicle.
At this stage only the front and rear bumpers will be designed according to
the above scheme.
At a later date the same scheme will be utilized for the sides of the vehicle,
keeping aesthetic
aspects of the vehicle intact.

Claims

2. CLAIMS:
1. A method for reducing the impact transmitted during a vehicular
collision or accident to the vehicle body or the occupants inside it.
This is achieved by utilizing a double bumper system with impact
load absorbing springs between the two bumper wall.
2. The method of harnessing the inner bumper to vehicle body,
alignment and harnessing of the outer bumper to the inner bumper
with springs in-between which act as multiple shock absorbers.
3. The method of installing the above systems at the front, rear and
sides of the vehicle
4. The method of design of the shock absorber springs to take the
impact loading of any vehicle traveling at a speed of 120 km/hour

3. DISCLOSURE:
METHOD AND APPARATUS FOR REDUCING IMPACT ON VEHICLE
AND OCCUPANTS DURING VEHICLE COLLISSIONS
Background of Invention:
During the collision/accidents of vehicles most of the impact is transferred
to
the vehicle body and the occupants via the bumpers. This leads to an
immense loss financially due to vehicle repair costs and to injuries or loss
of
life of the occupants of the vehicle.
This invention aims at drastically reducing the impact transferred during a
collision to the vehicle body and the occupants and thus considered as an
effort towards safety of the occupants and reducing the costs involved
consequent to the collision.
Brief description of the Invention:
The Enhanced Vehicle Safety Bumper (referred to as ESVB, in short)
consists of a double walled Bumper design with compression springs in
between. The design, rating, size, selection and number of compression
springs is such that the entire impact load transmitted during a collision via
the outer bumper wall would be absorbed by the compression springs.
The outer bumper wall would be the first to face the impact load and it would
transfer the same to the compression springs. The compression springs are
designed to absorb two opposite forces (both the vehicles in the accident) and
would compress and deflect under load such that there would be none or
minimal load transmission of impact to the inner bumper wall which is
attached to the vehicle frame. Thus the full collision load/impact is not
transmitted to the vehicle body and hence the occupants of the vehicle The
above design would cause minimal damage to the vehicle as well as to its
occupants during any accident or collision saving immense cost due to vehicle
damage or injuries to the occupants of the vehicle.
