Description
このため、下記特許文献2に開示の車両感応型センサでは、センサ・マスが支持部品の底面に形成された隆起部すなわち突出部上に置かれかつセンサ・マスには転がり半径が形成されている。これはセンサ・マスの接触面の尖点型支持を意図したものであり、塵埃粒子がセンサ・マスの傾動を妨げることはない。
複数の傾斜縁部は、これらの間に段状面を備えかつ内方のアクチュエータ延長部とセンサ・マスの接触面の外周縁部との間に配置されている。これにより、接触面の外周縁部が最外方の傾斜縁部を好都合に形成する。

Claims (5)
- 少なくとも車両感応態様で制御されるベルト巻回シャフトの、ブロッキングシステムを備えたセルフロッキング・ベルトリトラクタであって、車両感応センサがセンサ・マスを有し、該センサ・マスは、底部の接触面を介して平らな底面を備えた支持部品内で直立して配置され、これによりセンサ・マスは、車両の加速度が生じたときに支持部品内で傾動できるように配置され、センサ・マスは更に、関連するセンサ・レバーのためのアクチュエータ延長部を介して支持部品の底面の開口を通って延びている構成のセルフロッキング・ベルトリトラクタであって、センサ・マス(10)の接触面(11)は、少なくとも2つの傾斜縁部(16)を形成すべく段状の形状を有し、これにより、センサ・マス(10)の休止直立位置において、内方の中央アクチュエータ延長部(12)から出発して傾斜縁部(16)の間で外方に延びている段状面(15)が、この段状面(15)と支持部品(13)の底面(14)との間に、センサ・マス(10)が傾動したとき塵埃粒子を受け入れることができる空間(18)を形成するように、支持部品(13)の底面(14)に対してそれぞれ所定の距離を隔てて配置されていることを特徴とするセルフロッキング・ベルトリトラクタ。
- 前記傾斜縁部(16)の間で延びている段状面(15)が、支持部品(13)の底面(14)に対して平行に配向されることを特徴とする請求項1記載のベルトリトラクタ。
- 前記複数の傾斜縁部(16)は、これらの間に段状面(15)を備えかつ内方のアクチュエータ延長部(12)とセンサ・マス(10)の接触面(11)の外周縁部との間に配置されていることを特徴とする請求項1または2記載のベルトリトラクタ。
- 前記接触面(11)の外周縁部が最外方傾斜縁部(16)を形成していることを特徴とする請求項3記載のベルトリトラクタ。
- 前記段状面(15)の底面(14)に対する距離は、傾斜縁部(16)に形成される各重心角(α)が、直ぐ内方に隣接する傾斜縁部(16)に形成される重心角(α)(ここで、重心角(α)とは、傾斜縁部(16)からセンサ・マス(10)の重心(19)へと引かれる連結線(20)と、当該傾斜縁部(16)において、この同じ傾斜縁部(16)と直ぐ内方に隣接する傾斜縁部(16)との間の連結線(21)に対して引かれた垂線(22)との間で測定した角度である)より僅かに小さくなるように、それぞれ設定されていることを特徴とする請求項1〜4のいずれか1項記載のベルトリトラクタ。
