DESCRIPTION:
BRIEF SUMMARY
This invention relates to an improved webbing harness restraint, particularly for use by adults and children, particularly in motor vehicles, aircraft, marine craft, militry vehicles and other transport vehicles.
BACKGROUND OF THE INVENTION
Harness restraints in motor vehicles are usually of the lap type, lap and sash type, or full harness. The lap type, and lap and sash type are not ideal, for the belts do not fully restrain the person, and the full harness type includes a number of buckles and release mechanisms.
It is known that in a safety harness, one of the weak points is the provision of joins, and the provision of buckles on the end or ends of the various straps. Thus in a full harness various seams and joins are required where buckles are fitted.
It is an object of this invention to provide a harness restraint which provides a full harness restraint on a wearer.
It is a further object to provide a harness restraint in which a minimum of belts or straps are used with a corresponding minimum of joins and buckles.
It is a still further object to provide a harness restraint in which the straps are easily fitted to the user, and which can be easily unlatched or unbuckled.
BRIEF STATEMENT OF INVENTION
According to this invention there is provided a harness restraint for a person in a seat, the restraint comprising a pair of shoulder straps each anchored through the rear of the seat portion, and a crotch strap passing around each shoulder strap to draw these together in the area of the crotch to have a lap belt effect.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the invention applied to a childs car seat.
FIG. 2 shows the invention applied to a vehicle seat, and
FIG. 3 shows a further embodiment.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring firstly to FIG. 1, the invention is applied to a childs car seat 1, having a seat portion 2 and a back portion 3 mounted on a back frame 4 and base 5. The childs seat 1 is adapted to be secured in position on a vehicle seat by seat belts (not shown) fitted to the vehicle.
In this embodiment the shoulder straps 6 are adjustably attached at their ends 7 to the upper end of the seat back 3 at a position above the childs shoulders, the straps being provided with adjustment devices 8. Each strap 6 then passes downwardly through between the seat 2 and back portion 3 on the same side as its attachment at the top of the back portion 3, and are securely located to a fixed member on the seat 1. Each strap 6 can be joined to the fixed member, or alternatively the two straps 6 can be formed from a single strap passing around and through an anchorage on the seat 1. In this way, the straps 6 are a single length of belting and located by adjustment devices on the upper end of the seat back 3.
The crotch or leg strap 9 is attached to the seat portion 2 by a fixture 10 and a buckle 11. The strap 9 passes up between the legs around the shoulder strap 6 so that the straps 6 and both legs of strap 9 are looped together at about the crotch area of the child. In this way the straps 6 pass from the shoulder down to the crotch area and then over the hips to the anchorage. In this way the child is securedly held in the seat, the straps over the shoulders preventing bodily movement forward about the hips, and the crotch strap 9 and straps 6 prevent the body sliding down along the seat.
To fit the restraint, the child is seated, the straps 6 are then placed over the shoulders and then the crotch strap 9 is passed through behind both straps 6 and then fastened by its buckle 11. Hence one buckle only is used to fully restrain the child in the restraint.
An alternative version to be used by adults is shown as FIG. 2 where the restraint is fitted to a vehicle. In this example the shoulder straps 12 are formed of a single strap passing from the back 13 of the seat to anchorage points 14 on a fixture of the vehicle, such as a roll bar 15. The strap 12 passes downwardly to the floor from the seat 16 and around anchorage loops 17. The strap 12 is adjusted by adjustment 20. The crotc
