Automobile front deck structure

Claim 2

Front deck structure of an automobile body which comprises a dash panel assembly, a front pillar assembly at each side of the dash panel assembly and a longitudinally extending reinforcement assembly, said front pillar assembly including lower and upper pillar structures which are connected together with an overlapped relationship, said front pillar assembly having outer and inner panels respectively providing an outer surface and an inner surface of said front pillar assembly, said dash panel assembly including a dash panel extending transversely and having a side edge adjacent to the outer surface of each front pillar assembly, said longitudinal reinforcement assembly including outer and inner panels which respectively have rearward extensions having rear edges adjacent to the dash panel, said outer panel of the front pillar assembly and said extension of the outer panel of the longitudinal reinforcement assembly being formed with outwardly bent flanges which are welded together with the side edge of the dash panel interposed therebetween, said inner panel of the front pillar assembly and said extension of the inner panel of the longitudinal reinforcement assembly being formed with laterally bent flanges which are welded to the dash panel so that the inner panel of the pillar assembly is substantially opposite to the extension of the inner panel of the longitudinal reinforcement assembly with the dash panel interposed therebetween.

Claim 3

Front deck structure in accordance with claim 1 in which said rearward extension of the inner longitudinal panel of the longitudinal reinforcement assembly is separately formed from the inner longitudinal panel and connected thereto by welding.

Claim 4

Front deck structure in accordance with claim 2 in which said rearward extension of the outer longitudinal panel is formed separately from the outer longitudinal panel and connected thereto by welding.

Claim 5

Front deck structure in accordance with claim 1 in which a corner reinforcement panel is provided to extend between the dash panel and the longitudinal reinforcement assembly so that the connection between the dash panel and the longitudinal reinforement assembly is strengthened.

Claim 6

Front deck structure in accordance with claim 1 in which the inner and outer panels of the longitudinal reinforcement assembly are integral with each other by being connected through an upper longitudinal panel and an additional reinforcement member is provided to form a structure of a closed cross-section.

Claim 7

Front deck structure of an automobile body which comprises a dash panel assembly, a front pillar assembly at each side of the dash panel assembly and a longitudinally extending reinforcement assembly, said front pillar assembly including inner upper and inner lower members and outer upper and outer lower members, said inner upper and outer upper members being connected together to provide an upper pillar structure of closed cross-section, said inner lower and outer lower members being connected together to provide a lower pillar structure of closed cross-section, said inner and outer lower members being superposed on the inner and outer upper members and connected therewith, said dash panel assembly including a transversely extending dash panel which has opposite sides adjacent to said front pillar assemblies, said longitudinally extending reinforcement assembly including an inner longitudinal panel and an outer longitudinal panel which together form a reinforcement structure of a closed cross-section, said inner longitudinal panel having a rearward extension extending toward said dash panel and formed at rear end with a laterally bent flange with which said rearward extension is connected to said dash panel, said outer longitudinal panel having a rearward extension extending toward said dash panel and formed at rear end with a laterally outwardly bent flange, said outer lower member of the front pillar assembly having a laterally outwardly bent flange which is connected with said flange on said outer longitudinal panel with said dash panel interposed therebetween, said inner upper member of the front pillar assembly having a laterally bent flange which is connected to the dash panel so that the inner upper member of the front pillar assembly is substantially opposite to the rearward extension of the inner longitudinal panel of the longitudinal reinforcement assembly.

Claim 8

Front deck structure of an automobile body which comprises a dash panel assembly, a front pillar assembly at each side of the dash panel assembly and a longitudinally extending reinforcement assembly, said front pillar assembly including inner upper and inner lower members and outer upper and outer lower members, said inner upper and outer upper members being connected together to provide an upper pillar structure of closed cross-section, said inner lower and outer lower members being connected together to provide a lower pillar structure of closed cross-section, said inner and outer lower members being superposed on the inner and outer upper members and connected therewith, said dash panel assembly including a transversely extending dash panel which has opposite sides adjacent to said front pillar assemblies, said longitudinally extending reinforcement assembly including an inner longitudinal panel and an outer longitudinal panel which together form a reinforcement structure of a closed cross-section, said inner longitudinal panel having a rearward extension extending toward said dash panel and formed at rear end with a laterally bent flange with which said rearward extension is connected to said dash panel, said outer longitudinal panel having a rearward extension extending toward said dash panel and formed at rear end with a laterally outwardly bent flange, said outer lower member of the front pillar assembly having a laterally outwardly bent flange which is connected with said flange on said outer longitudinal panel with said dash panel interposed therebetween, said inner upper member of the front pillar assembly having a laterally bent flange which is connected to the dash panel so that the inner upper member of the front pillar assembly is substantially opposite to the rearward extension of the inner longitudinal panel of the longitudinal reinforcement assembly.
