Abstract

An energy absorbing unit is interposed between the body of a vehicle and a vehicle seat. The unit comprises an external frame comprising a pair of substantially vertical bars (6) and a bearing member (5) located in each bar. An internal frame comprising a transverse bar (3) is pivotally located in the bearings (5). The transverse bar contains a central bearing (4) into which is pivotally located a longitudinal bar (1). Plate members (2) are attached either side of the bar (1). Substantially flat plate members (7 and 8) are attached to the vertical bars (6). A plurality of springs (9 and 10) are located in two sets, between plates (2 and 7) and (2 and 8). In use acceleration or deceleration of the vehicle causes the seat to rotate about the transverse bar (3) the springs absorb energy to protect the occupant from shock loading in the event of an accident, see Figures 6-7. The seat may also move laterally in the event of a side impact see Figure 11. Bearings (4 and 5) may act in combination to provide a gimbal movement in two axes. The unit may be located at the upper part of the seat see Figures 10 and 11, under the seat, see Figures 12-14 or in both positions see Figures 15 - 17. Longitudinal bar (1) may also be extended to provide a mounting support see Figures (8-11). The unit may also be adapted to protect a child car seat see Figures 18-22.

Description

Intelligent Seat Safety System (ISSS) This invention relates to car seat
occupant's safety.
In the event of a car accident, forces are generated. Forces are then absorbed by all fixed parts of the car. The force is finally transmitted to seat occupants (passengers). The direction of transmission of the force begins from the body of the car passing through the chassis, seats, and finally the forces are transmitted to the passengers. There after, passengers collide with solid car components (steering wheel, dash board, doors, windshield, side windows, etc...) forcefully. As a result, passenger injuries are proportional to the initial force of impact and range from superficial cuts and bruises to fatal internal organ damage.
In the effort of minimizing car passenger injuries, the present invention proposes a device, here referred to as the Intelligent Seat Safety System (ISSS), linking the seat with the body of the car. The device, the Intelligent Seat Safety System (ISSS), forms the only means of communication between the seat and the body of the car. The Intelligent Seat Safety System (ISSS) is composed of two frames, internal and external, communicating with each other through bearings and springs. The internal frame comprises a rotating longitudinal bar which is stabilized be a bearing situated in the centre of a horizontal bar. The horizontal bar is stabilized by two bearings (one on each end) that link all the mobile parts of the internal frame to the external frame. The rear half of the longitudinal bar (behind the central bearing) is fixed to a strong plate on each side. Shock absorbing springs are fixed to the plates of the longitudinal bar at one end and to the plates of the external frame at the other end. The external frame is composed of two parallel C-shaped bars fixed to bearings at both ends of the horizontal bar, two strong plates fixed to the upper and lower ends of the side bars.
The car seat is fitted to the system on one side and the system is fixed to the body of the car on the other side. Therefore, there is no direct connection between car seats and the body of the car. In addition to that, impact forces are transmitted first to the system were they are substantially absorbed with the minimum of the impact forces being transmitted to the passenger. The result is a marked enhancement of passenger safety. The Intelligent Seat Safety System (ISSS) absorbs front, rear and side impacts.
An example of the invention will now be described by referring to the accompanying drawings: - Figure 1: shows a 3-dimensional front view of the Intelligent Seat Safety System (ISSS) according to the invention.

The Intelligent Seat Safety System (ISSS) The Intelligent Seat Safety System (ISSS) is composed of two parts, internal and external frames. The internal frame comprises a rotating longitudinal bar (1) which is stabilized be a central bearing (4) situated in the centre of a horizontal bar (3). The horizontal bar (3) is stabilized by two side bearings (5) (one on each end) that connect the internal frame to the external frame and allow independent movement of each frame. The rear half of the longitudinal bar (1), behind the central bearing, is fixed to a strong (middle) plate (2) on each side. Two sets of shock absorbing springs (9) and (10) connect the middle plates (2) of to the upper (7) and lower (8) plates of the external frame. The upper set shock absorbing springs (9) connect the middle plates (2) to the upper plate (7) while the lower set of shock absorbing springs (10) connect the middle plates (2) to the lower plate (8).
The external frame is composed of two parallel bars (6) incorporating the side bearings (5) at both ends of the horizontal bar (3), strong upper (7) and lower (8) plates are fixed at both ends of the side bars (6) joining the side bars (6) together. The longitudinal bar (1) forms one end of the Intelligent Seat Safety System (ISSS) while the side bars (6) form the other end of the system. One end is connected to the car seat and the other end is connected to the body of the car (the floor of the cabin) or vice versa. Either way the Intelligent Seat Safety System (ISSS) forms the only link between the seat and the rest of the car. Thus, the seat can move independent of the body of the car.
The function of the bearings and shock absorption springs is to stabilize and absorb the movement as one frame will be mobile while the other frame is less mobile or static.
The rotation of the longitudinal bar (1) provides a wide range of side movement for the seat and the rotation of the horizontal bar (3) provides a wide range of front and rear movement for the seat.
The system uses a unique seat suspension setup that provides a controlled and stabilized multi-direction mobility for the seats in order to absorb and divert the forces generated by car impact away from car seat occupants.
Therefore, forces generated by collisions are re-distributed and greatly absorbed by the Intelligent Seat Safety System (ISSS) instead of being totally transmitted to the body of the passenger.
Assuming that the longitudinal bar (1) is fixed to the seat and the side bars (6) are fixed to the floor of the car (body of the car), the internal frame and the seat will form the mobile unit in the event of a car impact while the external frame and the body of the car are relatively less mobile or static.
In the event of an impact of a car that is not fitted with the Intelligent Seat Safety System (ISSS), the car will lose up to 100% of its momentum while car occupants will travel towards the site of impact at speeds equivalent to the initial speed of the car before the impact. This is primarily because of the fact that the different parts of the car acts as a single unit and the passenger act as separate freely mobile unit. Therefore the forces generated by that impact will be totally transmitted to the passenger. As a result the passenger will collide with solid car components (steering wheel, dash board, doors, windshield, side windows, etc...) forcefully resulting in major disabling injuries.
In the event of an impact of a car that is equipped with the Intelligent Seat Safety System (ISSS), the car will still lose up to 100% of its momentum.
But instead of transmitting 100% of the forces generated by the impact to the passenger, first, forces will be distributed to both the passenger and the seat; second, the impact forces will be absorbed by strong shock absorbing springs that connect the seat to the body of the car. The strong shock absorbing springs will oppose the movement of the internal frame, the seat, and the passenger, stabilize it, and absorb it. The end result is a massive reduction in the amount of impact generated forces being transmitted to the passenger therefore providing the passenger with the most possible protection, safety, and comfort.
The Intelligent Seat Safety System (ISSS) provides extreme levels of safety and comfort to both children and adult car occupants. The setup provides protection against front, back and side impacts. Furthermore, the system enhances the function of airbags and seatbelts and reduces the amount of trauma generated by them in extreme impact situations. The setup is applicable for both adult and child car seats. The setup could be integrated within the seat material. For use in adults and child car seat, the strength of the shock absorbing springs is pre-determined by the manufacturer.
The Intelligent Seat Safety System (ISSS) can be linked to the rear upper part of the back rest of a child car seat, can be integrated to the upper part of the back rest of an adult car seat, and can be linked to the base of the adult car seat cushion.
The Intelligent Seat Safety System (ISSS) can be fitted to car seats without interfering with the seat height/tilt/position adjustment mechanism.
Special emphasis has to be put on child car seat as the system provides optimum protection to vital organs in the head and chest of the child providing him/her with the optimum level of protection, safety and comfort.
