Description
技术领域
本发明涉及座椅, 是一种能够整体调节的座椅。
背景技术
用于火车、 飞机和汽车上的乘客座椅, 大部分是调节靠背角度, 以达到缓解乘客长时 间座车的疲惫感。 由于座椅的座面相对于座椅的靠背呈垂直状态, 因此, 当座椅靠背向后 调整时只能改变乘客的座姿, 使乘客背部向后倾斜, 腿部向前移动, 乘客呈半躺状况, 但 是,这种姿式使乘客的腰部悬在空中,人体重量集中在臀部和背部,无法解除乘客的疲劳感。 为此, 申请人于 2002年设计了一种能够通过调节座椅的座面角度, 使座椅靠背与座面同时 调整的座椅。 这种座椅可使座面后端向下移动, 使座面呈向后倾斜, 这时乘客臀部随座面 倾斜向后移动, 使乘客体重能均匀分布在座面和靠背上, 使乘客有较好的舒适感。 但是, ' 这种座椅的不足在于: 当座面后部向下移动时, 只能使靠背后倾, 座面在水平方向没有移 动距离。 因此, 这在很大程度上限定了靠背向后倾斜的角度。 由于座椅靠背向后倾斜角度 较大时, 必定占用后排空间, 从而影响后排乘客活动空间。 如果靠背向后倾斜角度较小时, 乘客的舒适度则明显下降, 较难缓解乘客的疲劳感。 如何在规定的空间内尽可能安装多排 座椅的前提下, 使座椅靠背的调节角度加大的同时, 增加乘客的舒适度是目前本领域技术 人员长期以来研究的重要课题。
发明内容
本发明的目的是, 提供一种整体调节座椅, 它能够根据乘客的需要调整座椅靠背倾斜 角度的同时, 使座面向前移动并向下倾斜, 能够实现在固定的空间内, 完成大角度靠背的 调整, 使乘客具有极高的舒适度。
本发明为实现上述目的通过以下技术方案实现: 一种整体调节座椅, 包括座面和靠背,
