VEHICLE SEAT BELT DEVICE

PROBLEM TO BE SOLVED: To provide a vehicle seat belt device which inhibits excessive vibration of a tube member of a pretensioner included in a retractor.SOLUTION: The invention includes: a door 15 which opens and closes an entrance 11 formed at a vehicle body 1; and a retractor device 25 provided at the door. The retractor device includes: a frame 70 attached to the door; a retractor 80 assembled into the frame, the retractor 80 from which a seat belt 33 may be drawn; and a pretensioner 90 which pulls in the seat belt drawn from the retractor when a predetermined or larger impact force is applied to the vehicle body. The pretensioner includes a tube member 92 where one end part is connected with the retractor and the other end part extends to a periphery, the tube member which may generate a force for pulling in the seat belt. A space between the retractor and the other end part of the tube member includes a vibration inhibition part 60 which inhibits vibration of the tube member in an opening/closing direction of the door. 【課題】本発明は、リトラクタに装備されるプリテンショナのチューブ部材の過大な振れが抑えられる車両のシートベルト装置を提供する。【解決手段】本発明は、車体１に形成された乗降口１１を開閉するドア１５と、ドアに設けられたリトラクタ装置２５とを有し、リトラクタ装置は、ドアに取着されるフレーム７０と、同フレームに組み付けられシートベルト３３が引出可能なリトラクタ８０と、所定以上の衝撃力が車体に加わると、リトラクタから引き出されたシートベルトを引き込むプリテンショナ９０とを有し、プリテンショナは、一端部がリトラクタに接続され、他端部が周囲に延び、シートベルトを引込む引込み力を発生可能なチューブ部材９２を有し、リトラクタとチューブ部材の他端部との間は、ドアの開閉方向におけるチューブ部材の振れを抑える振れ抑制部６０を有するものとした。【選択図】図３
