ABSTRACT:
A location board in a covering member of a vehicle seat, which is used in such a seat assemblage which involves bonding at least two cover sections of a covering member to a cushion member and is of such type that can be teared along the sewn jointed portion of those two cover sections for attaining a resultant seat. The location board is formed with a notched portion laying along an imaginary sewing line. In the seat assemblage, the two cover sections of covering member are sewn to one section of the location board, thus forming a series of sewing holes in the location board. The notched portion is elongated in reference to the sewing holes at such a length that permits a tearing to occur from the notched portion towards the sewing holes in a direction to prevent creation of a pointed projection at the teared edge of residual section of location board in the resultant seat at a stage of tearing off another section of the same location board.
