Description

办公椅升降靠背的弹性倚靠复位装置
技术领域
本实用新型涉及的是在靠背支撑单元上滑设有可弹性回缩的弹性支持单元，并令该弹性支持单元设有弹性部连结于靠背的下端处，进而让靠背在进行升降调整时，令该弹性部对于靠背下端的弹性支持作用，完全不会受到影响。 
背景技术
现代人待在办公室的时间远比待在家里的时间长，一款舒适的办公椅就扮演着相当重要的角色，不过长时间不变的坐姿却也会造成乘坐者下背痛的发生，而目前市售宣称可防止下背痛发生的腰带护具，其功效仍未被证实，而过度信赖腰带可能带来反效果，对于计算机工作使用者因长时间静态坐姿可能导致的下背痛，则必须考虑选择一张合适的坐椅。 
一般而言，躯干直立或稍微向前的坐姿(此时大腿与上半身的夹角小于90度)，腰椎椎间盘承受的压力大于站姿，故长时间静态坐姿(缺少姿势变化)，也容易导致疲劳，所以常看到久坐之后，人们的身体就会动来动去，来舒缓不适。同时靠背支撑部份身体重量，减少腰椎受力，让肌肉也可以得到放松，所以工作时尽量使腰部得到背靠的支撑对降低下背疲劳很重要；所以椅面太深坐下去的时候，腰椎无法接触到靠背而得不到支撑，或靠背太高或太低时，则令腰椎也无法得到适当的支撑。 
于是，申请人即开发一可随着椅具靠背升降的腰部弹性倚靠装置，并申请的CN2010201162437专利，其主要是包括一可以调整高度的靠背下端处与椅具之间枢接一具弹性伸缩的弹性支持单元，而该支持单元是包括两相互穿合、且两者之间设有弹簧拉制而可弹性缩合的支持内杆与支持外杆，并令弹性支持单元的两端枢固处，分别套设可令支持单元与靠背朝向预定方向摆动的弹簧，进而除了让靠背可做不同的高度调整外，更令靠背下端的腰靠部位具有弹性倚靠的作用，让不同身高的乘坐者都能符合人体 工学的倚靠外，更令乘坐者的腰部获得舒适的支撑，让长时间乘坐者的腰背疼痛更可以减轻。 
不过，为了让靠背可以自动下降复位，在支撑单元与靠背之间设置了一向下拉掣靠背的弹簧，让靠背随时保持被向下拉的力量，但却也造成靠背下端的向后退缩，所以又必须设置另一弹簧来抵消靠背的向后退缩的作用以外，更要能提供乘坐者腰部弹性倚靠的能力，所以整个构造不但显得相当复杂，同时也因上述两弹簧的相互消长作用，即当靠背升得越高时，靠背的下端仍会有稍为退缩的现象，进而令乘坐者腰部的弹性倚靠作用不足，让原本要提供乘坐者腰部弹性倚靠的作用，大打折扣，无法达到更完整的预期效果。 
实用新型内容
本实用新型的目的在于提供一种办公椅升降靠背的弹性倚靠复位装置，以改善前述公知靠背在升降调整时，会发生弹性倚靠作用的消长问题。 
为实现上述目的，本实用新型提供的办公椅升降靠背的弹性倚靠复位装置，包括一靠背支撑单元、一滑设于该靠背支撑单元上而能升降定位的靠背，并在靠背支撑单元稍下方处设一可连结于靠背下端处的弹性倚靠复位装置，其中该弹性倚靠复位装置包括一被弹簧向下拉掣、而沿着靠背支撑单元滑行的滑件，并令该滑件上伸设一其末端连结于靠背下端处的弹性部。 
所述的办公椅升降靠背的弹性倚靠复位装置，其中该靠背支撑单元稍下方处设一滑道，并又设一覆盖遮盖于滑道上，使该滑件容设于覆盖与滑道之间，且拉掣滑件的弹簧上端固定于滑件上端处，而弹簧的下端则固定于滑道上，同时该滑件上的弹性部类呈倒U型。 
本实用新型的有益效果是，通过上述的弹性倚靠复位装置在靠背进行不同高度位置的调整时，除了通过弹簧而使靠背保持被向下拉掣的力量以外，同时无论靠背被调整在任何位置时，更能通过弹性部让靠背的下端腰靠部位处，始终能保持预定的弹性支撑力量，进而令乘坐者腰部获得合适的支撑。

具体实施方式
本实用新型是一种装设于靠背支撑单元与靠背下端之间的弹性倚靠复位装置，其目的是在靠背进行高度调整定位后，靠背原有的腰部弹性倚靠作用，仍然可以保持完整而不受影响。 
本实用新型解决其技术问题所采用的技术方案是：设一可滑行于一靠背支撑单元上而升降定位的靠背，并在该靠背下端与该靠背支撑单元之间设一弹性倚靠复位装置，且该弹性倚靠复位装置是包括一受弹簧向下拉掣而沿着靠背支撑单元滑行的滑件，并令滑件上端伸设一其末端连结于靠背下端处的弹性部。 
上述方案中，该靠背支撑单元稍下方处设一遮覆有一覆盖的滑道，并令该滑件容设于覆盖与滑道之间，且该弹簧的上、下端分别固定于滑件的上端处与滑道的下方处，同时滑件的弹性部是类呈倒U型。 
下面结合附图和实施例对本实用新型进一步说明。 
请参阅图1所示，本新型的靠背支撑单元2是被锁固于椅具上而设置靠背1，即该靠背支撑单元2是通过其上方处滑设且能定位的连结支持单元3两端，以枢固组件4与背靠1上方两侧的枢固部11枢固连结，而在靠背1的下端处与靠背支撑单元2之间则设一弹性倚靠复位装置5连结于 其间，同时该弹性倚靠复位装置5的结构，并与靠背1、靠背支撑单元2之间的连结情形，如图2、3与图4、5所示，即该靠背支撑单元2的稍下方处设一滑道21，并在该滑道21内容设一滑件51，且设一覆盖53遮盖于滑道21上，即让滑件51被容纳在滑道21与覆盖53之间，同时在滑件51的背后凹设一长槽511，而在该长槽511中容设一弹簧52，并令该弹簧52的上端固定于滑件51上，而弹簧52的下端则固定于滑道21中，使得能通过该弹簧52对滑件51产生向下拉掣的作用。 
然后，再令该滑件51的上端延伸设一类呈倒U型的弹性部512，并令该弹性部512的下端513锁固于靠背1下端中间的固定部12处，进而通过该弹性部512对让靠背1的下端处产生弹性的顶推作用。 
至于前述的连结支持单元3与靠背支撑单元2之间的定位结构，并非本实用新型的诉求重点，所以并未有详细的揭示，但其动作的情形是当连结支持单元3逐渐向上升时，可以进行不同位置的定位，但当其上升至最高处时，连结支持单元3即可自由地向下滑落至最低处。 
请再结合图6、7所示，当靠背1沿着靠背支撑单元2的上端处，向上滑动调整至预定的高度时，靠背1的下端即会通过滑件51的弹性部512，令滑件51沿着靠背支撑单元2的滑道21而向上滑行，且该弹簧52即会对滑件51产生向下拉掣的作用，使得靠背1得以更稳固地定位住；并当靠背1上升至最高处时，即可通过该弹簧52的拉掣而使靠背1回复至最低的位置处；同时无论靠背1被调整至任何预定的高度处时，该弹性部512都能始终保持原来预定的弹性而不变形，进而让乘坐在椅具上的乘坐者腰部，不但可以确实地倚靠于靠1的下端部位处，更通过弹性部512的完整弹力，让乘坐者腰部可以获得舒适的弹性倚靠。
