Hey
Is it possible/allowed to mount seatbelts on to the cae of a geep. I have three point harnesses and dont want to: a) weld a peice across the two horizontal parts of the cage and then bolt the belts to that, like my Dad wants me to, b) have to bolt the belts to part of the floor where the chasis runs along.
Any info/thoughts would be greatly appreciated

Sorry thought these were cool.

The basics for harness mounting are as follows:
The anchorage points are one either side of the seat and then one to the rear for a 4x3 harness and two for a 4x4 harness.
All mounting points should accept 7/16" UNF high tensile steel threaded eyebolts.
The straps should run directly to their anchorage point with no obstruction or deviation. Straps should not be twisted and severe twists should not be induced by the installation when the harness is worn.
The lap belt/straps should pass through the sides of the seat not over it (ie racing seats with harness holes). This allows the pelvic region to be "wrapped" by the belt. The area of lap belt crossing should be below the anterior-superior iliac spines (bony part of the hip). On no account should the lap part of the belt be worn over the abdomen region.
The lap belt/straps must be fixed to their anchorage points vertically downwards and not forwards or rearwards of the hip joint. Thery should also be symmetrical and about 20" apart.
The distance between the seating surface and anchorage points should be kept to a minimum to prevent submarining.
The tail strap(s) should be horizontal to 20degrees below horizontal and as close to the shoulder as is practical for optimum restraint.
If there are twin tail strap anchorages these should be set about 12" to 20" apart. They should be measured from the central point of the seat.
The structure to which the harnesses are attached should be of a suitable construction to satisfy the regulations required for all seat belt/restraints.
I hope this helps you out.
