Abstract
Abstract A pillar construction for a vehicle body includes a steel pad formed from a resilient sheet steel and disposed between a pillar inner panel of a pillar main body and a pillar trim. In a secondary collision in which the pillar trim is subjected to a force directed outward of a vehicle body and deformed thereby, the steel pad produces a reaction force against deformation of the pillar trim at the initial stage of the secondary collision and substantially no reaction force at the final stage of the secondary collision.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
97 words
A pillar construction for a vehicle body comprising: a pillar main body having a pillar inner panel; a pillar trim supported on said pillar main body in such a manner as to cover said pillar inner panel; and a metal pad supported on said pillar inner panel and restrictedly movable through engagement with said pillar inner panel to produce a reaction force at an initial stage of reaction thereof in response to a force applied thereto from an inside of the vehicle body whereas being freely movable to produce substantially no reaction force after said initial stage.
Claim 2
Dependent Claim
97 words
A pillar construction for a vehicle body comprising: a pillar main body having a pillar inner panel; a pillar trim supported on said pillar main body in such a manner as to cover said pillar inner panel; and a metal pad supported on said pillar inner panel and restrictedly movable through engagement with said pillar inner panel to produce a reaction force at an initial stage of reaction thereof in response to a force applied thereto from an inside of the vehicle body whereas being freely movable to produce substantially no reaction force after said initial stage.
Claim 3
Dependent Claim
70 words
A pillar construction according to claim 1, wherein said metal pad has a central portion having a surface in contact with an inboard surface of said pillar inner panel, and has at least one side portion on a side of said central portion, said side portion having a protruded section located adjacent said pillar trim and a free end section located adjacent said inboard surface of said pillar inner panel.
Claim 4
Dependent Claim
36 words
A pillar construction according to claim 2, wherein said free end portion of said side portion of said metal pad is flanged so as to be parallel to said inboard surface of said pillar inner panel.
Claim 5
Dependent Claim
34 words
A pillar construction according to claim 2, wherein said pillar trim and said pillar inner panel define therebetween a space enabling said free end section of said metal pad to be movable freely therewithin.
Claim 6
Dependent Claim
41 words
A pillar construction according to claim 1, wherein said pillar trim has an integral support projection projecting from an outboard surface thereof toward said pillar inner panel, said metal pad being held between said support projection and said pillar inner panel.
Claim 7
Dependent Claim
73 words
A pillar construction according to claim 1, further comprising a bracket attaching said pillar trim to said pillar inner panel, said pillar trim having at an outboard surface thereof two corner portions opposing to each other and two integral ribs in a form of thin plate, said bracket having opposite end portions at which it is secured to said ribs, said metal pad being held between said bracket and said pillar inner panel.
Claim 8
Dependent Claim
15 words
A pillar construction according to claim 1, wherein said metal pad is made of steel.
Claim 9
Dependent Claim
97 words
A pillar construction for a vehicle body comprising: a pillar main body having a pillar inner panel; a pillar trim installed on said pillar main body in such a manner as to cover said pillar inner panel; and a steel pad formed from steel sheet and installed on said pillar inner panel, said steel pad being restrictedly movable to produce a reaction force at an initial stage of movement thereof in response to a force applied thereto from an inside of the vehicle body and freely movable after said initial stage to produce substantially no reaction force.
Claim 10
Dependent Claim
97 words
A pillar construction for a vehicle body comprising: a pillar main body having a pillar inner panel; a pillar trim installed on said pillar main body in such a manner as to cover said pillar inner panel; and a steel pad formed from steel sheet and installed on said pillar inner panel, said steel pad being restrictedly movable to produce a reaction force at an initial stage of movement thereof in response to a force applied thereto from an inside of the vehicle body and freely movable after said initial stage to produce substantially no reaction force.
Claim 11
Dependent Claim
99 words
A pillar construction for a vehicle body comprising: a pillar-shaped main body having a pillar inner panel; a pillar trim installed on said main body in such a manner as to cover said pillar inner panel; and a resilient sheet steel member serving as a pad, supported on said pillar inner panel and cooperative with said pillar inner panel and adapted to produce a reaction force at an initial stage of application of a force from an inside of the vehicle body against said sheet steel member while adapted to produce substantially no reaction force after said initial stage.
Claim 12
Dependent Claim
99 words
A pillar construction for a vehicle body comprising: a pillar-shaped main body having a pillar inner panel; a pillar trim installed on said main body in such a manner as to cover said pillar inner panel; and a resilient sheet steel member serving as a pad, supported on said pillar inner panel and cooperative with said pillar inner panel and adapted to produce a reaction force at an initial stage of application of a force from an inside of the vehicle body against said sheet steel member while adapted to produce substantially no reaction force after said initial stage.
Claim 13
Dependent Claim
67 words
A pillar construction according to claim 9, wherein said sheet steel member has a central portion having a surface in contact with an inboard surface of said pillar inner panel, and has a side portion connected to said central portion, said side portion having a protruded section located adjacent said pillar trim and a free end section located adjacent said inboard surface of said pillar inner panel.
Claim 14
Dependent Claim
21 words
A pillar construction according to claim 10, wherein said side portion of said sheet steel member has a U-like cross section.
Claim 15
Dependent Claim
37 words
A pillar construction according to claim 10, wherein said free end portion of said side portion of said sheet steel member is flanged so as to be parallel to said inboard surface of said pillar inner panel.
Claim 16
Dependent Claim
35 words
A pillar construction according to claim 10, wherein said pillar trim and said pillar inner panel define therebetween a space enabling said free end section of said sheet steel member to be movable freely therewithin.
Claim 17
Dependent Claim
47 words
A pillar construction according to claim 9, wherein said pillar trim has an integral support projection projecting from an outboard side surface thereof toward said pillar inner panel, said sheet steel member being held between said support projection of said pillar trim and said pillar inner panel.
Claim 18
Dependent Claim
74 words
A pillar construction according to claim 9, further comprising a bracket attaching said pillar trim to said pillar inner panel, said pillar trim having at an outboard surface thereof two corner portions opposing to each other and two integral ribs in a form of thin plate, said bracket having opposite end portions at which it is secured to said ribs, said sheet steel member being held between said bracket and said pillar inner panel.
