Instrument panel for automotive vehicles

Claim 2

An instrument panel for an automotive vehicle, comprising a one-piece, elongated sheet material structure adapted to extend between the front pillars of the vehicle and having a panel portion forming a passenger's head impinging zone, said sheet material structure including upper and lower spaced panel sections, a rear end panel section connecting said upper and lower panel sections at the rear end adjacent a vehicle seating area, said rear end panel section being essentially planar and angularly offset from said upper and lower panel sections, and a pair of side panel sections located adjacent the front pillars, said lower spaced panel sections extending downwardly and forwardly from the lower edge of the rear end panel section, said panel portion forming the head impinging zone being provided in said upper panel section, wherein said sheet material structure is provided with a weakened panel portion at a location other than said panel portion forming the passenger's head impinging zone, said weakened panel portion being adapted to promote the absorption and dissipation of impact energy by weakening part of said sheet material structure permitting controlled deformation and breakage, and wherein said weakened panel portion is provided in said lower panel section.

Claim 3

An instrument panel as set forth in claim 1, wherein said weakened panel portion comprises a stepped panel portion.

Claim 4

An instrument panel as set forth in claim 2, wherein said stepped panel portion is formed to be thinner than the remaining part of said lower panel section.

Claim 5

An instrument panel as set forth in claim 2, wherein said stepped panel portion is formed with a plurality of slits which are arranged along a transverse line at suitable spacing.

Claim 6

An instrument panel as set forth in claim 2, wherein said weakened panel portion comprises a thin-wallled panel portion which is thinner than the remaining part of said lower panel section and which has an exterior surface substantially flush with that of the remaining part of said rear panel section.

Claim 7

An instrument panel for an automotive vehicle, comprising a one-piece, elongated sheet material structure adapted to extend between the front pillars of the vehicle and having a panel portion forming a passenger's head impinging zone, said sheet material structure including upper and lower spaced panel sections, a rear end panel section connecting said upper and lower panel sections at the rear end adjacent a vehicle seating area, said rear end panel section being essentially planar and angularly offset from said upper and lower panel sections, and a pair of side panel sections located adjacent the front pillars, said lower panel section extending downwardly and forwardly from the lower edge of said rear end panel section, said panel portion forming the head impinging zone being provided in said upper panel section, wherein said sheet material structure is provided with a weakened panel portion at a location other than said panel portion forming the passenger's head impinging zone, said weakened panel portion being adapted to promote the absorption and dissipation of impact energy by weakening part of said sheet material structure permitting controlled deformation and breakage, and wherein said weakened panel portion is provided in at least one of said side panel sections.

Claim 8

An instrument panel for an automotive vehicle, comprising a one-piece, elongated sheet material structure adapted to extend between the front pillars of the vehicle and having a panel portion forming a passenger's head impinging zone, said sheet material structure including upper and lower spaced panel sections, a rear end panel section connecting said upper and lower panel sections at the rear end adjacent a vehicle seating area, said rear end panel section being essentially planar and angularly offset from said upper and lower panel sections, and a pair of side panel sections located adjacent the front pillars, said lower panel section extending downwardly and forwardly from the lower edge of said rear end panel section, said panel portion forming the head impinging zone being provided in said upper panel section, wherein said sheet material structure is provided with a weakened panel portion at a location other than said panel portion forming the passenger's head impinging zone, said weakened panel portion being adapted to promote the absorption and dissipation of impact energy by weakening part of said sheet material structure permitting controlled deformation and breakage, and wherein said weakened panel portion is provided in at least one of said side panel sections.

Claim 9

An instrument panel as set forth in claims 1 or 6, wherein said panel portion forming the head impinging zone is further provided to said rear end panel section.

Claim 10

An instrument panel as set forth in claim 6 wherein said weakened panel portion comprises a thin-walled panel portion which is thinner than the remaining part of said side panel section and which has an exterior surface substantially flush with that of the remaining part of the said side panel section.

Claim 11

An instrument panel as set forth in claim 6, wherein said weakened panel portion comprises a slit.

Claim 12

An instrument panel as set forth in claim 6, wherein said weakened panel portion comprises a stepped panel portion.

Claim 13

An instrument panel as set forth in claim 10, wherein said stepped panel portion is formed with a slit.

Claim 14

An instrument panel as set forth in claim 10, wherein said stepped panel portion is formed to be thinner than the remaining part of said side panel section.
