Description
この出願は、2019年9月10日に提出された中国特許出願第201910855970.2号の優先権を主張している。
1.発明の分野
本発明は、チャイルドセーフティシートに関する。
チャイルドセーフティシートは、典型的には、自動車車両に使用され、偶発的な衝突の際に子供を適切に拘束する。一般に、ラッチデバイス及びトップテザーは、チャイルドセーフティシートを車両に取り付けるために、それぞれ、サポートベース及びチャイルドシートの上部に提供され得る。さらに、前記チャイルドセーフティシートには、前記ラッチデバイスと前記トップテザーが正しく取り付けられていない場合に介護者に警告できるアラート装置が付いている場合がある。例えば、中国出願の公開番号CN109177830Aは、ラッチデバイス及びトップテザーの位置を検出するためのセンサを使用するアラート装置、及び前記センサから検出信号を受信し、制御信号をアラートエミッタに出力する信号処理ユニットを開示する。残念ながら、この構造は複雑であり、応答時間が長くなる可能性があり、部品の損傷又は欠陥が原因で障害が発生する可能性がある。
本願は、構造が単純であり、車両シートへのチャイルドセーフティシートの不適切な設置を効果的に警告することができるアラートシステムを有するチャイルドセーフティシートについて説明する。
拘束デバイス12は、アイドル位置から展開位置に伸ばすことができ、これは、前述のように、前記スイッチアクチュエータ152を前記スイッチ14に向かって移動して引く。これにより、前記スイッチングアクチュエータ152は、前記スイッチ14と接触するか、又は前記スイッチ14に近接して配置することができ、これにより、前記スイッチ14を閉状態から開状態に切り替えることができる。その結果、前記スイッチ13b及び14と前記アラートデバイス17とからなる直列回路が開かれ、電流が前記アラートデバイス17に流れない。したがって、前記アラートデバイス17は、前記拘束デバイス11及び12がそれぞれの展開位置にあるときにアラート信号の発信を停止する。
