Abstract

Embodiments of a car seat include an outer protective shell, an inner seat, a suspension system connecting and permitting relative movement between the inner seat and the outer protective shell for shock isolation, and a harness adapted to hold an occupant to the inner seat and not attached to the outer protective shell. In an accident, regardless of the direction in which the seat is facing and regardless of whether the result is a sudden acceleration and/or deceleration, the inner seat will move inside the frame, and the suspension system will absorb some, much, or all of the energy. Energy not absorbed by the suspension system may be absorbed by the inner seat itself and/or an anchor system used to connect the car seat to a vehicle. The frame of the seat will remain structurally intact in almost all circumstances thereby protecting the occupant of the car seat.

Claims

1. A car seat for an occupant, comprising:

an outer protective shell having a major dimension extending along a longitudinal axis;

a plurality of anchor boxes extending at an angle with respect to the longitudinal axis; and

an inner seat coupled to the outer protective shell.

2. A car seat according to claim 1, further comprising:

a harness adapted to hold the occupant in the inner seat.

3. A car seat according to claim 1, wherein:

said anchor boxes each extend perpendicular to said longitudinal axis.

4. A car seat according to claim 1, wherein:

said anchor boxes each are constructed to receive and attach to at least one of a LATCH connector and an ISOFIX connector.

5. A car seat according to claim 1, wherein:

said anchor boxes each include a housing, a sleeve coupled to the housing, and at least one insert interposed between said sleeve and said housing.

6. A car seat according to claim 5, wherein:

at least one insert is formed of a compressible material.

7. A car seat according to claim 6, wherein:

compressible material includes foam.

8. A car seat according to claim 5, wherein:

said at least one insert has a first cross-sectional area at a first location relative to said longitudinal axis and a second cross-sectional area different than said first cross-sectional area at a second location removed from said first location relative to said longitudinal axis.

9. A car seat according to claim 5, wherein:

said at least one insert comprises a plurality of inserts.

10. A car seat according to claim 1, further comprising:

a suspension system coupled to said inner seat and to said outer protective shell, said suspension system suspending the inner seat substantially within the outer protective shell and permitting relative movement therebetween and shock-isolating said inner seat from said outer protective shell.

11. A car seat system for removably coupling a car seat to a vehicle having at least one car seat anchor, the system comprising:

a car seat having at least one anchor; and

a tether strap having a first connector at a first end of said tether strap and having a second connector at a second end of said tether strap,

wherein said first connector is removably attached to the at least one car seat anchor of the vehicle and said second connector is removably attached to the at least one anchor of the car seat.

12. A car seat system according to claim 11, wherein:

said car seat includes an inner seat, a shock isolation apparatus coupling the inner seat and said outer protective shell and permitting relative movement therebetween, and a harness adapted to hold the occupant in the inner seat and not attached to the outer protective shell.

13. A car seat shock isolation system for a car seat having a wall and connected to a vehicle, the system including:

a shock absorbing washer seated in the wall of the car seat and

a strap extending through said washer and coupled to the car seat, said strap having an end portion adjacent to said washer that is constructed to apply pressure to said washer in response to movement of said strap.

14. A car seat shock isolation system according to claim 13, wherein:

said washer has an inner flange disposed on an inner side of the wall of the car seat, an outer flange disposed on an outer side of the wall of the car seat, and a web extending between the inner flange and the outer flange, wherein the end portion of the strap is adjacent to the outer flange.

15. A car seat shock isolation system according to claim 14, wherein:

said washer is formed of foam.

16. A car seat for an occupant, comprising:

a) an outer protective shell;

b) an inner seat;

c) a suspension system coupling and permitting relative movement between said inner seat and said outer protective shell, said suspension system suspending said inner seat substantially within said outer protective shell;

d) a harness adapted to hold the occupant in the inner seat and not attached to the outer protective shell; and

e) a plurality of padding elements wherein,

said outer protective shell has an inner surface and said plurality of padding elements are located on said inner surface of said outer protective shell, and wherein the plurality of padding elements extend from the inner surface of the outer protective shell to the inner seat and at least one of the padding elements always contacts the inner seat.
