  • Patent number: 5713634
    Abstract: A seat back structure of a vehicle seat with a headrest provided thereon, in which a blow-molded plastic seat back frame is utilized, with an anchor bracket pre-assembled integrally therein. The headrest is supportively secured on that anchor bracket. A connecting element, such as a locking element, is provided between the anchor bracket and a body of vehicle, so that a load applied to the headrest is dispersed through the anchor bracket and connecting element toward the body of vehicle, which does not require any reinforced elements and designs to the seat back frame per se and thus permits the seat back frame to be made light in weight.

  • Patent number: 3981906
    Abstract: Alkyl 4,4'-(ethylenedioxy)bis-benzoates having improved properties such as anti-oxidation and anti-coloration are prepared in high yield and selectivity by, at the first step, reacting an excess alkyl p-hydroxybenzoate with a recycling alkyl p-(2-chloro-ethoxy)benzoate with heating in the presence of an alkali carbonate and an inert organic solvent until almost said alkyl p-(2-chloroethoxy)benzoate is consumed to produce an alkyl 4,4'-(ethylenedioxy)bis-benzoate and at the second step adding ethylene dichloride to the reaction system and continuing the heating to produce an alkyl p-(2-chloroethoxy)benzoate which is recycled, and separating the alkyl 4,4'-(ethylenedioxy)bis-benzoate produced.
