<p>PROBLEM TO BE SOLVED: To prevent impairment of an outward appearance of a seat surface, even if a sewing part of mutual cover pieces of a seat cover is arranged in a deep position in a seat pad.SOLUTION: A seat 1 is provided by pulling a sewing part (a second sewing part 21C) of mutual cover pieces 21 of a back cover 20 in a back pad 10, and comprises a first sewing part 21B for joining mutual pull-in parts 21A of the cover piece 21 pulled in the back pad 10 in an area closer to a surface of the back cover 20 than the second sewing part 21C. The first sewing part 21B joins the mutual pull-in parts 21A by weaker binding power than the second sewing part 21C, and always holds the mutual pull-in parts 21A in a joined state, but is ruptured by inputting a large load for unreasonably separating the mutual pull-in parts 21A by strongly applying body pressure from an occupant to the back cover 20 by the occurrence of a collision of a vehicle, and is constituted so as to receive the body of the occupant up to the second sewing part 21C.</p> |
