Abstract
The invention discloses a three-point safety belt installation reinforcement structure. The three-point safety belt installation reinforcement structure comprises a front crossbeam, a rear crossbeam, a left longitudinal beam, a right longitudinal beam and at least two middle longitudinal beams. The front crossbeam and the rear crossbeam are parallel to each other. The left longitudinal beam, the right longitudinal beam and the middle longitudinal beams are parallel to one another. The front crossbeam and the rear crossbeam are perpendicular to the left longitudinal beam, the right longitudinal beam and the middle longitudinal beams. A closed rectangle is formed by the front crossbeam, the rear crossbeam, the left longitudinal beam and the right longitudinal beam in an enclosed mode. Two middle longitudinal beams are located between the left longitudinal beam and the right longitudinal beam.
