Abstract

A fragmentary hand steering wheel contains a number of inner fragment shells 3 and outer fragment shells 2 that are supported by an arch effect and rotated by a an electrical device or devices 5 in order to change the hand steering wheel solid structure into a fragmented non-solid structure. The steering wheel comprises pins 4 and spokes 7. In the fragmenting state, the pins 4 move the inner fragments 3 to align with the outer fragments 2. The invention has advantages if an air bag 6 fails. The invention allows the structure of the steering wheel to change in a crash, thus reducing the potential for harm to the driver.

Description

The fragmentary hand steering wheel

Background

This invention relates to making the hand steering wheel of motor propelled vehicles and non motor propelled vehicles that require a hand steering wheel for steering and direction purposes safer When a vehicle is involved in a frontal or a side collision the degree of violence and risks can vary from low to medium or deadly depending on the speed and weight of the vehicle involved, and in certain cases the driver and his vehicle can receive not one frontal or a side impact but multiple impacts all depends on the speed of the vehicle Before its collision with one or more objects. In most cases the correct deployment of the air bag can only offer the driver a maximum of l5ooo of a second or so of protection against the solid hand steering wheel, its steering column and also the car windshield this can be achieved by around 2000 ponds of detonation force and an airbag deployment speed that can exceed 200 miles in hour. Sometimes airbags deploy at the wrong time and can even fail to deploy altogether. Serious injuries and even death can occur from airbags failing to open. Or Starts to deflate before making contact with the coming forward body of the driver there for making its protective nylon airbag less effective or useless this can be caused by a number of factors.

* Sensor damage that does not sense the impact on the car lmproper sensor and wiring installation that does not Initiate deployment improper packing of the airbag into the airbag compartment Malfunction with the deploying mechanism that prevents the airbag from being released in accidents where one or multiple frontal collisions can accrue, air bag failures can only put the dangers of the solid hand steering wheel back on the menu for mainly the Drivers head and knees, chest which can lead to severe facile disfigurements bone braking injures or even death.

Statement of invention

To overcome the dangers of the solid hand steering wheel and to increase the survivability chances of the drivers of motor propelled vehicles in the event of airbag premature deployment or airbag failures in accidents of motor propelled vehicles and non motor propelled vehicles that require a hand steering wheel for steering purposes in the event of a frontal or a side accident the present invention proposes a fragmentary hand steering wheel that contains a number of inner and outer fragments that are mechanically operated by an electrical device(S) that's responsible for rotating the inner fragments inside their outer fragments shells in order to change the solid hand steering wheel structure into a non solid fragmented structure Adva ntages 1. The fragmentary hand steering wheel will provide the drivers of motor propelled vehicles that require a hand steering wheel for steering with a safe and fragmented hand steering wheel surfaces in the event of a frontal or a side accident of one or multiple impacts taking place 2. It will provide the drivers of motor propelled vehicles and non motor propelled vehicles that require a hand steering wheel for steering with a back up safety system in the event of air bag malfunction, premature deployment, or air bag failures in the form of a solid hand steering wheel that can be fragmented into a non solid state in the event of an accident taking place for safety reasons 3 the fragmentary hand steering wheel can work jointly with the air bag sensor or separately with its own sensor(s) to achieve maximum safety results 4. The fragmentary hand steering wheel can still be used as a the vehicle steering device after its activation by the edges of it spoke(s) For safety reasons
