Preferably, substantially all the seat belt is mounted external the first and second interior envelopes, and the web of the seat belt extends flat along the first side of the seat back between the retractor and the belt guide and the axis of rotation of the retractor extends generally parallel to the first track. Advantageously, the belt guide is mounted on a second member which is moveable with respect to a first member which is fixed to the seat back. Advantageously, the seat back includes an external frame having an upper horizontal arm, a lower horizontal arm, a first vertical arm and a second vertical arm and an internal reinforcing member secured to the first vertical arm proximate the upper horizontal, secured to the lower horizontal and secured to the second vertical arm proximate the upper horizontal arm.
