Description
ENERGY ABSORBING STEERING WHEEL HORN PAD
FIELD OF INVENTION
This invention relates to steering wheel horn pad for vehicles and more particularly relates to energy absorbing type steering wheel horn pad.
BACKGROUND OF INVENTION
In case of a vehicle, steering wheel is provided to maneuver the vehicle in desired direction. Basically steering wheel comprises of steering wheel rim, energy absorber provided inside the steering wheel and horn pad. In the event of crash collision, the driver's head hits the steering wheel and may lead to serious or fatal injury. Therefore it is necessary to make the steering wheel soft enough to promote the absorption of energy contained with the driver's head.
The steering wheel also contains an additional function for blowing of the horn. In order to actuate the horn function, horn pad is provided, at the centre of the steering wheel, above central hub. Energy absorbing structure has been provided below the horn pad to dissipate the kinetic energy of the driver's head in case of crash collision.
Conventionally a separate secondary structure, preferably metallic, is provided below the horn pad for absorbing the head impact energy.
The main drawback associated with said conventional horn pad is that it requires more number of parts and in turn induces more cost.
OBJECTS OF INVENTION
The main object of this invention is to provide steering wheel horn pad for vehicles having adequate provision to absorb the head energy generated during vehicle collisions.
Another object of this invention is to provide steering wheel horn pad for vehicles which is simple in construction & cost effective.
Yet another object of this invention is to provide steering wheel horn pad for vehicles which is easy to manufacture.
STATEMENT OF INVENTION
Steering wheel horn pad comprising of one or more snap guides, horn actuating devices, at least one energy absorbing structure at the center portion of horn pad and set of multiple ribs provided at either side of said energy absorbing structure wherein said snap guides, said horn actuating devices, said energy absorbing structure and said ribs are provided integrally on inner side of said horn pad.
Steering wheel horn pad wherein said energy absorbing structure is further provided with through hole.
Steering wheel horn pad wherein said set of multiple ribs are provided with a provision to accommodate horn actuating means.
Steering wheel horn pad wherein said multiple ribs are provided with depressions.
Steering wheel horn pad wherein said multiple ribs are provided without depressions
Steering wheel horn pad wherein said horn pad is provided with multiple transverse ribs.
Steering wheel horn pad wherein said snap guides, horn actuating devices, ribs and energy absorbing structure are made with similar material.
