Claim 3

An instrument panel structure as defined in claim 1, wherein said guide means is provided on said instrument panel.

Claim 4

An instrument panel structure as defined in claim 1, wherein further guide means is integrally provided on said cover.

Claim 5

An instrument panel structure of an automotive vehicle, having a collapsible steering shaft extending towards a driver seat of the automotive vehicle and an instrument panel including an opening formed therein, said instrument panel having mounted thereon a cluster gauge and being disposed in front of said seat, said opening formed in said instrument panel receiving said collapsible steering shaft, said instrument panel structure comprising: a cover having a hollow shell which is generally cylindrically shaped so as to cover an end portion of said collapsible steering shaft projecting above said instrument panel; a visor bank provided on said instrument panel to surround said cluster gauge and formed with an open space overlapping said opening; and guide means disposed in said open space and provided between said visor bank and an end of said cover for guiding movement of said hollow shell during a collision, the guide means having an inwardly bent flap section forming a surface for engaging said end of said cover and sliding over said hollow shell as it sinks into said opening when said collapsible steering shaft axially collapses during said collision.

Claim 6

An instrument panel structure of an automotive vehicle, having a collapsible steering shaft extending towards a driver seat of the automotive vehicle and an instrument panel including an opening formed therein, said instrument panel having mounted thereon a cluster gauge and being disposed in front of said seat, said opening formed in said instrument panel receiving said collapsible steering shaft, said instrument panel structure comprising: a cover having a hollow shell which is generally cylindrically shaped so as to cover an end portion of said collapsible steering shaft projecting above said instrument panel; a visor bank provided on said instrument panel to surround said cluster gauge and formed with an open space overlapping said opening; and guide means disposed in said open space and provided between said visor bank and an end of said cover for guiding movement of said hollow shell during a collision, the guide means having an inwardly bent flap section forming a surface for engaging said end of said cover and sliding over said hollow shell as it sinks into said opening when said collapsible steering shaft axially collapses during said collision.

Claim 7

An instrument panel structure as defined in claim 4, wherein said guide means is formed as a part of said visor bank.

Claim 8

An instrument panel structure of an automotive vehicle, having a collapsible steering shaft extending towards a driver seat of the automotive vehicle and an instrument panel including an opening formed therein, said instrument panel having mounted thereon a cluster gauge and being disposed in front of said seat, said opening formed in said instrument panel and receiving said collapsible steering shaft, said instrument panel structure comprising: a cover having a hollow shell which is generally cylindrically shaped so as to cover an end portion of said collapsible steering shaft projecting above said instrument panel; a visor bank provided on said instrument panel to surround said cluster gauge and formed with an open space overlapping said opening, said visor bank comprising a plateau wall section surrounding an upper side and opposite ends of an area within which said cluster gauge exists and a lower cross beam; and guide means at least partly formed by said lower cross beam, said guide means disposed in said open space and having a surface for guiding said hollow shell to sink into said opening when said collapsible steering shaft axially collapses during a collision.

Claim 9

An instrument panel structure of an automotive vehicle, having a collapsible steering shaft extending towards a driver seat of the automotive vehicle and an instrument panel including an opening formed therein, said instrument panel having mounted thereon a cluster gauge and being disposed in front of said seat, said opening formed in said instrument panel and receiving said collapsible steering shaft, said instrument panel structure comprising: a cover having a hollow shell which is generally cylindrically shaped so as to cover an end portion of said collapsible steering shaft projecting above said instrument panel; a visor bank provided on said instrument panel to surround said cluster gauge and formed with an open space overlapping said opening, said visor bank comprising a plateau wall section surrounding an upper side and opposite ends of an area within which said cluster gauge exists and a lower cross beam; and guide means at least partly formed by said lower cross beam, said guide means disposed in said open space and having a surface for guiding said hollow shell to sink into said opening when said collapsible steering shaft axially collapses during a collision.

Claim 10

An instrument panel structure as defined in claim 6, wherein said visor bank further comprises wall extension sections disposed on opposite sides of said area so as to provide said open space therebetween in combination with said lower cross beam, each said wall extension section having a surface curved from a top surface of said plateau wall section to said instrument panel for guiding a combination switch lever, which extends from said cover and is able to turn about an axis of rotation of said steering shaft, when said cover sinks into said opening during a collision.

Claim 11

An instrument panel structure as defined in claim 6, wherein said generally cylindrically shaped hollow shell comprises upper and lower halves of shells separately formed and connected to each other by a plurality of fitting pins.

Claim 12

An instrument panel structure as defined in claim 8, wherein said upper and lower halves of shells are made of plastic material.

Claim 13

An instrument panel structure as defined in claim 8, wherein said fitting pin is formed with an annular groove so as to allow itself to be sheared so as to separate said generally cylindrically shaped hollow shell into said upper and lower halves of shells when said cover sinks into said opening.
