Abstract
Abstract A steering wheel having an operating portion, a hub portion, a spoke portion, an impact energy absorbing member located on the hub portion for absorbing impact energy, and a pad including a hard insert and a soft cover member integrally covering the insert for covering at least an impact energy absorbing member and a spoke portion. The insert has a plurality of divided parts or a portion or portions of thin wall section to improve an impact energy absorbing effect of the impact energy absorbing member independently of the rigidity of the pad, without the deterioration of the pad.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
A steering wheel comprising: an operating portion; a hub portion for connection with a steering shaft, said hub portion being located generally centrally of said operating portion; a spoke portion connecting said operating portion to said hub position for transmitting steering motion applied to said operating portion, to the steering shaft via the spoke portion and the hub portion; an impact energy absorbing member located on said hub portion for absorbing impact energy; a pad covering said impact energy absorbing member and said spoke portion, said pad including a hard insert integrally covered by a soft cover member, said hard insert comprising a plurality of separate hard insert parts which are divided from one another by at least one bendable portion each of which provides a line of preferential bendability, whereby said pad can be bent when a force impacts said soft cover member, by causing bending movement of said parts along at least one said line of preferential bendability
Claim 2
Dependent Claim
160 words
A steering wheel comprising: an operating portion; a hub portion for connection with a steering shaft, said hub portion being located generally centrally of said operating portion; a spoke portion connecting said operating portion to said hub position for transmitting steering motion applied to said operating portion, to the steering shaft via the spoke portion and the hub portion; an impact energy absorbing member located on said hub portion for absorbing impact energy; a pad covering said impact energy absorbing member and said spoke portion, said pad including a hard insert integrally covered by a soft cover member, said hard insert comprising a plurality of separate hard insert parts which are divided from one another by at least one bendable portion each of which provides a line of preferential bendability, whereby said pad can be bent when a force impacts said soft cover member, by causing bending movement of said parts along at least one said line of preferential bendability
Claim 3
Dependent Claim
22 words
The steering wheel of claim 1, further including: fastener means securing each said hard insert part to said impact energy absorbing member.
Claim 4
Dependent Claim
78 words
The steering wheel of claim 2, wherein: said hard insert parts include a centrally-located hard insert part and a plurality of peripherally-located hard insert parts, and said peripherally-located hard insert parts each having first portions bounded by said impact energy absorbing member, and second portions which project beyond said impact energy absorbing member and overly said spoke portion, at least a part of said at least one bendable portion thereby being bounded by said impact energy absorbing member.
Claim 5
Dependent Claim
47 words
The steering wheel of claim 3, wherein: each said bendable portion comprises at least one connecting element having a thinner portion which is thinner than said hard insert parts and respective one of said hard insert parts are integrally joined by said at least one connecting element.
Claim 6
Dependent Claim
40 words
The steering wheel of claim 4, wherein: each said bendable portion is constituted by a series of said connecting elements, each said thinner portion extending across said line of preferential bendability and being spaced from each other said thinner portion.
Claim 7
Dependent Claim
19 words
The steering wheel of claim 5, wherein: said series of connecting elements further includes openings through said hard insert.
Claim 8
Dependent Claim
27 words
The steering wheel of claim 4, wherein: each of said at least one connecting element is constituted by at least one continuous web adjoining a hollowed-out space.
Claim 9
Dependent Claim

The steering wheel of claim 7, wherein: said at least one connecting element is further constituted by a second continuous web which is spaced from said one continuous web by said hollowed-out space.
Claim 10
Dependent Claim
51 words
The steering wheel of claim 1, wherein: each said bendable portion comprises at least one connecting element, each said connecting element having a thinner portion which is thinner than said hard insert parts and respective ones of said hard insert parts are integrally joined by said at least one connecting element.
Claim 11
Dependent Claim
42 words
The steering wheel of claim 9, wherein: said at least one bendable portion is constituted by a series of said connecting elements, each said thinner portion extending across said line of preferential bendability and being spaced from each other said thinner portion.
Claim 12
Dependent Claim
19 words
The steering wheel of claim 10, wherein: said series of connecting elements further includes openings through said hard insert.
Claim 13
Dependent Claim
27 words
The steering wheel of claim 9, wherein: each of said at least one connecting element is constituted by at least one continuous web adjoining a hollowed-out space.
Claim 14
Dependent Claim
33 words
The steering wheel of claim 12, wherein: said at least one connecting element is further constituted by a second continuous web which is spaced from said one continuous web by said hollowed-out space.
