Abstract: A track assembly for a vehicle includes an upper track slidably mounted in a lower track. A seat belt buckle mounting bracket is attached to the upper track and connects a fixed seat belt to the upper track. The seat belt buckle mounting bracket includes first and second angularly disposed legs, with the first leg attached to the upper track and the second leg attached to a fixed seat belt buckle. The attachment structure mounts the seat belt buckle mounting bracket in a first, normal operating position in which the second leg of the bracket extends upward from a side wall of the upper track. The attachment structure permits the seat belt buckle mounting bracket to rotate from the first position under a force applied through the fixed seat belt to a second position in which the second leg of the bracket is substantially aligned with the longitudinal axis of the upper track to place the first and second legs of the bracket in tension with the applied force.

Abstract: A track assembly for a vehicle includes an upper track slidably mounted in a lower track. A seat belt buckle mounting bracket is attached to the upper track and connects a fixed seat belt to the upper track. The seat belt buckle mounting bracket includes first and second angularly disposed legs, with the first leg attached to the upper track and the second leg attached to a fixed seat belt buckle. The seat belt buckle mounting bracket is stationarily mounted in a first, normal operating position in which the second leg of the bracket extends upward from a side wall of the upper track, but rotates from the first position under a force applied through the fixed seat belt to a second position in which the second leg of the bracket is substantially aligned with the longitudinal axis of the upper track to place the first and second legs of the bracket in tension with the applied force. The second position provides a strong geometry position for the seat belt buckle mounting bracket.
