Abstract: A paint resin composition which does not appreciably attack an old coated film or a substrate to be coated, said composition consisting essentially of(A) a copolymer having a glass transition point of from -30.degree. C. to +50.degree. C., a number average molecular weight of from 4,000 to 20,000 and a weight average molecular weight/number average molecular weight ratio of from 1.8 to 10 and obtained by copolymerizing (a-1) 1 to 50% by weight of a vinyl monomer having a hydroxyl group, (a-2) 0 to 5% by weight of a vinyl monomer having a carboxyl group, (a-3) 0 to 80% by weight of a polyester resin having a copolymerizable unsaturated bond, (a-4) 10 to 80% by weight of a vinyl monomer having a side-chain alkyl group with 4 to 8 carbon atoms, and (a-5) 4 to 49% by weight of another vinyl monomer copolymerizable with the monomers (a-1) to (a-4), the total proportion of these monomers being 100% by weight, in the presence of a radical initiator in a nonpolar organic solvent having an aniline point of 7.degree.

Abstract: A passive seat belt for an automobile is disclosed. A guide rail is mounted to a sashless door or a roof side rail, and a movable anchor member is adapted to move in the groove of the guide rail so that the one end of a belt, connected to the free end of the movable anchor member, may be kept at a certain height higher than the door panel for preventing the belt from contacting a part of a body of a driver or a passenger. The guide rail may be straight and positioned horizontally or may be bent at the rear end of the door. The movable anchor member may be locked by a locking stop. The guide rail is covered by a decorative trim piece. The movable anchor member is reinforced by a reinforcing member mounted to the door, the pillar, or the like of the automobile.
