PURPOSE:To provide a crew with an appropriate constraint condition all the time by movement with a seat for the crew when adjusting the location of the seat while positively supporting impact loads to a car body under all emergent conditions of a car. CONSTITUTION:A laminar arm 20 axially supported to a seat base 12 by means of a fitting bolt 18 is inserted between character-like guide plates 34, and the guide plates 34 are fastened to a seat base 12 by means of bolts 18, 36. A slender portion material 44, such as, a steel wire, etc. is pierced between the bent portions 42 of the guide plates 34 and an end surface of the laminar arm 20, and one end of the slender portion material 44 is fixed to a floor portion material 10 of a car by means of a bolt 48 and another end is fastened to a pin 50 fixed to the seat base 12 through a tension spring 52. An end surface 54 of the laminar arm 20 is formed in an arched shape, and the slender portion material 44 is held and pressurized by means of the end surface 54 when collision, etc., thus supporting impact loads to a belt 30 by means of the floor portion material 10. |
