Abstract: A seat supports an occupant of a vehicle. The seat comprises a seating frame member for providing a surface to support the occupant and a back frame member extending away from the seating frame member. The back frame member defines a U-shaped cavity. A boss is coupled to the back frame member within the U-shaped cavity. A fastening element extends through the boss and the back frame member. The fastening element deforms the boss and the back frame member when a force above a predetermined value is applied to the back frame member thereby causing the back frame member to rotate relative to the seating frame member. Allowing the back frame member to rotate relative to the seating frame member reduces an impact force transferred from the seat to the occupant caused by the force above the predetermined value.
