Abstract
Abstract Herein disclosed is an improved belt anchoring device which is incorporated with a slidable seat. The device uses a monolithic metal bracket for connecting a slide rail of the seat to a pin holder which is slidable on a toothed anchor stay fixed to the vehicle floor together with the seat. Upon application of abnormal impact load thereto through the seat belt, the bracket is forced to bend to permit locking engagement between the pin holder and the anchor stay thereby assuredly and safely dispersing the impact load to the vehicle body through the belt anchoring device.

Claim 1
Independent Claim
313 words
A seat belt anchoring device for use with a seat which is slidable on a floor by means of slide rails, comprising: a slide rail on which the seat is mounted and a stationary rail on which said slide rail is slidably disposed, said seat thereby being slidable relative to the floor; an anchor stay pivotally connected to said floor and extending in the direction of seat sliding, said anchor stay being formed with a plurality of longitudinally aligned notches; a pin holder slidably disposed on said anchor stay, said holder having a portion to which an end of the seat belt is fixed; a stopper pin held by said pin holder, said stopper pin being brought into locking engagement with one of said notches of the anchor stay when said pin holder is inclined by a given degree relative to said anchor stay; and a bracket mounted on said slide rail to move therewith, said bracket being connected to said pin holder and including means for bending when a certain impact load is applied thereto, said bending means being said bracket to such a degree as to permit the inclination of said pin holder by said given degree; wherein said bracket includes first and second portions which intersect at a generally right angle and are respectively secured to the slide rail and the pin holder, the apex of said right angle forming a folded ridge extending parallel to said direction of seat sliding, said bending being at a portion of said bracket other than said folded ridge wherein said first portion includes a wider part and a narrower part, said narrower part extending in the same direction as that of the anchor stay, and wherein said bracket is formed with a groove which extends diagonally across said narrower part in order to increase the deformability of the first portion of the bracket.

A seat belt anchoring device for use with a seat which is slidable on a floor by means of slide rails, comprising: a slide rail on which the seat is mounted and a stationary rail on which said slide rail is slidably disposed, said seat thereby being slidable relative to the floor; an anchor stay pivotally connected to said floor and extending in the direction of seat sliding, said anchor stay being formed with a plurality of longitudinally aligned notches; a pin holder slidably disposed on said anchor stay, said holder having a portion to which an end of the seat belt is fixed; a stopper pin held by said pin holder, said stopper pin being brought into locking engagement with one of said notches of the anchor stay when said pin holder is inclined by a given degree relative to said anchor stay; and a bracket mounted on said slide rail to move therewith, said bracket being connected to said pin holder and including means for bending when a certain impact load is applied thereto, said bending means being said bracket to such a degree as to permit the inclination of said pin holder by said given degree; wherein said bracket includes first and second portions which intersect at a generally right angle and are respectively secured to the slide rail and the pin holder, the apex of said right angle forming a folded ridge extending parallel to said direction of seat sliding, said bending being at a portion of said bracket other than said folded ridge wherein said first portion includes a wider part and a narrower part, said narrower part extending in the same direction as that of the anchor stay, and wherein said bracket is formed with a groove which extends diagonally across said narrower part in order to increase the deformability of the first portion of the bracket.
Claim 3
Dependent Claim
28 words
A seat belt anchoring device as claimed in claim 1, in which said groove is provided by cutting the upper side of said first portion of the bracket.
Claim 4
Dependent Claim
24 words
A seat belt anchoring device as claimed in claim 1, in which said groove is provided by pressing said first portion of the bracket.
Claim 5
Dependent Claim
47 words
A seat belt anchoring device as claimed in claim 3, further comprising a spacer which is interposed between said narrower part of the first portion and the slide rail in order to define a clearance between the wider part of the first portion and the slide rail.
Claim 6
Dependent Claim
239 words
A seat belt anchoring device for use with a seat which is slidable on a floor by means of a slide rail, comprising: an anchor stay pivotally connected to said floor and extending in the direction of seat sliding, said anchor stay being formed with a plurality of longitudinally aligned notches; a pin holder slidably disposed on said anchor stay, said holder having a portion to which an end of the seat belt is fixed; a stopper pin held by said pin holder, said stopper pin being brought into locking engagement with one of said notches of the anchor stay when said pin holder is inclined by a given degree relative to said anchor stay; and a bracket having a first end secured to said pin holder and a second end secured to an upper surface of said slide rail, said bracket including means for bending along a line parallel to said surface of said slide rail upon application of a force above a predetermined level being applied to said seat belt end, said bending resulting in the inclination of said pin holder by said given degree, wherein said bending means bending includes a flat portion of said bracket adjacent said second end, said flat portion being parallel to said surface of said slide rail and including a groove means for increasing the bendability of said bracket, and wherein said groove means comprises a cut in said flat portion.
Claim 7
Dependent Claim
