A seat includes a seat bottom, a seat back, a seat mounting structure configured to support the seat bottom and the seat back, the seat mounting structure configured to slidably couple to the rail assembly, and an occupant restraint system including a seat belt coupled to a retractor assembly. The retractor assembly is configured to slidably couple to the rail assembly such that the retractor assembly moves along the rail assembly as the seat mounting structure is moved along the rail assembly, the occupant restraint system configured to transfer load to the rail assembly disposed in the vehicle floor.

A safety belt automatic adjustment apparatus includes a safety belt buckle fastening assembly, a safety belt retractor and a linking component. The safety belt buckle fastening assembly is rotatably connected to a seat body of a child safety seat and for connecting with a safety belt buckle. The safety belt retractor is used for retracting a safety belt, and the safety belt retractor includes a restraining assembly for restraining a movement of the safety belt in a predetermined direction. The linking component is installed between the safety belt buckle fastening assembly and the safety belt retractor, and the safety belt buckle fastening assembly rotates to drive the linking component and the restraining assembly, so as to restrain or release the safety belt winding around the safety belt retractor. The safety belt automatic adjustment apparatus has advantages of automatic adjustment for the safety belt, simple structure, convenient operation and enhanced safety.

A webbing take-up device is provided with a spool and a stopper member. A webbing is taken up onto the spool. The spool includes a webbing insertion hole into which the webbing is inserted. The stopper member secures an end portion of the webbing at the spool by engaging with a periphery portion of the webbing insertion hole. The webbing take-up device is also provided with load bracing portions (a portion at an axial direction one side of a first serrated portion and a portion at an axial direction another side of a rod portion that are formed at a torsion shaft). The load bracing portions are disposed at the diametric direction inner side of the spool relative to the stopper member and are disposed to be close to the spool. The load bracing portions brace a load that is applied to the spool from the webbing via the stopper member.

A utility vehicle is provided with a seat frame disposed below a seat for a crew and supporting the seat, the utility vehicle includes:

a seatbelt apparatus configured to hold the crew sitting on the seat; in which

the seat frame includes a projection projecting outward in a vehicle width direction from the seat and covering a top of a fuel tank,

the seatbelt apparatus includes a retractor supporting an end of webbing so as to freely wind the webbing, and the retractor is attached to the projection.
