For seatbelt anchorage test, three loads are acting on seat. In which, F1 & F3 are seat belt load which are acting ontrack assembly. F2 is load of seat. Now, we want to calculate load on track under seat belts. Assume, track angle is 0° from horizontal. Also we can consider weight of seat 18kg.

Angle of shoulder belt load =3 degree

Angle of belly belt load = 3.7 degree

Assuming,

F1= 13500 N

F3= 13500 N

F2= 20*18=360 kg = 360* 9.81=3531.6 N

Distance from pivot to CG= 83 mm

Distance from pivot to F1= 95 mm

Distance from pivot to F2= 70 mm

L= Distance from CG to pivot point horizontally= 6 mm

Track peel out strength, Fp

Fp*L = (F1* sin α)* 95 + (F3* sin β)* 70 + F2*83

= (13500* sin 3)*95+ (13500* sin 3.7)*70 +3531.6*83

=421226.69

Therefore, Fp= 421226.69/L= 70,204.5 N = 70.2 kN

Peel out strength for individual track= 70.2/2= 35.1 KN
