A seat for providing an improved level of protection to a child by reducing the amount of force restraining straps exert upon the child during a collision. The seat includes a seat frame and a cover positioned over the seat frame to provide comfort to a seat occupant. The seat frame includes a seat back with a slot for receiving a strap for restraining a seat occupant and an energy absorbing member. The energy absorbing member reduces the amount of force applied by the strap to the seat occupant during a sudden deceleration of the seat and comprises an elongated weakness area extending from a bottom edge of the slot. The energy absorbing member is adapted for progressive separation from the seat back during a sudden deceleration, whereby the strap is allowed to move forward, at a controlled rate, a predetermined distance during the sudden deceleration of the seat.
1. A seat, comprising:
(a) a strap for restraining a seat occupant;
(b) a seat frame having a seat back that includes a plurality of slots positioned in spaced-apart relation in a mid portion of the seat back such that each respective slot of the plurality of slots is configured for selectively receiving the strap; and
(c) the seat frame further including a plurality of energy absorbing members, each of the energy absorbing members being positioned on the seat back adjacent to the respective slot and mounted on a rearward side of the seat frame adjacent to the respective slot and being operatively associated with the respective slot for reducing the amount of force applied by the strap to the seat occupant during a sudden deceleration of the seat.
2. The seat according to claim 1 , wherein the plurality of energy absorbing members includes an area of reduced resistance to application of a force extending from a bottom edge of the respective slot, and adapted for separation from the seat back during a sudden deceleration, whereby the strap is allowed to move forward, at a controlled rate, a predetermined distance during the sudden deceleration of the seat.
3. The seat according to claim 2 , wherein the plurality of energy absorbing members decreases in size from the bottom of the seat back to the top of the seat back.
4. The seat according to claim 2 , wherein the plurality of energy absorbing members decreases in energy absorbing capacity from the bottom of the seat back to the top of the seat back.
5. The seat according to claim 1 , wherein the energy absorbing members are positioned between a rearward side of the seat frame and the strap, the energy absorbing members comprising a crushable material adapted for progressive crushing during a sudden deceleration, whereby the strap is allowed to move forward, at a controlled rate, a predetermined distance during the sudden deceleration of the seat.
6. The seat according to claim 5 , wherein the seat frame includes a plurality of energy absorbing members, each of the energy absorbing members being positioned on the rearward side of the seat back adjacent to the respective slot of the plurality of slots.
7. The seat according to claim 6 , wherein the plurality of energy absorbing members decreases in energy absorbing capacity from the bottom of the seat back to the top of the seat back.
8. The seat according to claim 1 , wherein the plurality of slots includes a bottom pair of slots, an intermediate pair of slots positioned above the bottom pair of slots, and a top pair of slots positioned above the intermediate pair of slots, and further wherein the seat back includes a first pair of energy absorbing members positioned adjacent the bottom pair of slots, and a second pair of energy absorbing members positioned adjacent the intermediate pair of slots.
9. The seat according to claim 8 , wherein the first pair of energy absorbing members have greater energy absorbing capacity than the second pair of energy absorbing members.
10. A seat, comprising:
(a) a seat frame having a seat back and a seat bottom, the seat back having an upper pair of slots, an intermediate pair of slots, and a bottom pair of slots for receiving a strap for restraining a seat occupant;
(b) the seat frame further including a first pair of energy absorbing members operatively associated with the bottom pair of slots and a second pair of energy absorbing members operatively associated with the intermediate pair of slots to allow the strap to move forward, at a controlled rate, a predetermined distance during a sudden deceleration of the seat, thereby reducing the amount of force applied by the strap to the seat occupant; and
(c) wherein the first pair of energy absorbing members has a greater energy absorbing capacity than the second pair of energy absorbing members, and the first and second pairs of energy absorbing members include an area of reduced resistance to application of a force extending from a bottom edge of each slot, and are adapted for separation from the seat back during a sudden deceleration, whereby the strap is allowed to move forward, at a controlled rate, a predetermined distance during the sudden deceleration of the seat.
11. The seat according to claim 10 , wherein the first and second pairs of energy absorbing members are positioned between a rearward side of the seat frame and each slot, the first and second pairs of energy absorbing members comprising a crushable material adapted for progressive crushing during a sudden deceleration, whereby the strap is allowed to move forward, at a controlled rate, a predetermined distance during the sudden deceleration of the seat.
