摘要:
A rear end collision shock absorbing unit wherein there are provided one-side member rotating in synchronization with either one side of the seat back side and the seat cushion side between members that turn mutually to enable tilting, and the other-side member rotating in synchronization with the other side, and a convex part is provided on the one-side member, a concave part or a through hole in which the convex part fits is provided in the other-side member, and when a rear end collision shock is applied, the convex part and the concave part or through hole are turned relatively and deformed in a fitted state, whereby rear end collision shock energy is absorbed.

An impact absorbing plate 31 is disposed between a front part 31z of the impact absorbing plate 31 and a vehicle body 11 so that a rupture generating part 44 ruptured by impact is extended in the front and rear direction of the vehicle, and the impact absorbing plate 31 is fixed to a front part 13a and a rear part 13b of the front seat bracket 13 provided in the vehicle body by rivets 33 and 33. A portion of front part 31z of the impact absorbing plate 31 is cut to form a cutoff part 45, and a front end 17a of a rail 17 provided in a seat section is attached to a convex part 35, which is molded so as to expand upward an inner side of the cutoff part 45, by a rivet 34.

N-substituted 3,4-dihydropyrimidine compounds of the formula: ##STR1## wherein R is straight, branched, cyclic or cyclo-straight alkyl having from one to four carbon atoms; and X.sup.1, X.sup.2 and X.sup.3 are the same or different and are hydrogen, halogen, lower alkyl having from one to four carbon atoms, lower alkoxy having from one to four carbon atoms, nitro, trifluoromethyl, hydroxy, or t-butyldimethylsilyloxy with the proviso that the case wherein X.sup.1, X.sup.2 and X.sup.3 are all hydrogen is not applicable have substantially strong and lasting vasodilative effects. Therefore, the compounds are useful as agents for treating disorders of the cardiovascular system, for example, antihypertensive agents, circulation improver and antianginal agents.
