选择办公椅基本要点

行业新闻  | 2015-11-18 10:57:29

选择要素一:人体工学设计
    一张理想办公椅,必须依照人体工程学而设计。人体工程学是研究人及其身体与工作、环境、设备之间的关系。一张能符合人体工学设计及制造出来的办公椅,将为使用者——无论其体重或坐姿——都带来舒适感。更重要者,可为使用者长时间静坐工作需要而提供护脊功能。同事帮助其减轻身体各部位压力,使血液循环顺畅,消除工作疲劳而提高工作效率。

选择要素二:牢固性
    办公椅为一种长时间及频繁性使用的办公家具。一张合格的椅子,通常可应使用5至10年。不理想的椅子,在经过一段短时间使用后,往往出现功能失效,螺丝松脱或杂音等现象,如此将会大大影响工作者情绪及工作效率。

重要部件及功能
【机械底盘】
为一张办公椅之最重要部分。最普遍的机械底盘功能可分为:椅背仰动;椅背与坐垫同步倾仰;椅背角度调校;坐垫前倾角度调校等。采购时须作适当评估及考虑,务求选用一张配备合适功能之椅子,符合实际工作需要。

【椅背高度及角度】
调校功能可为使用者提供适当之贴背支撑,协助使用者保持正确坐姿,以保护使用者之脊骨不因长时间之工作而受损。

【腰托】
在棉状椅背上为一种不可缺乏之设计项目,其功能在于帮助使用者保持正确坐姿,减轻脊骨承受压力,并避免脊骨因不良坐姿二造成扭曲。

【网布材料】
现在已很普遍应用于办公椅之椅背。由于具弹性及富柔软性,使椅背之设计可更突出腰托部分,但当人体后靠于椅背时,网布将自动调节适应,不论哪种体形使用者,椅背都能紧贴承托其整个背部。

【椅座高度】
可适当调校,对一张办公椅同样重要。不同身高使用者可随意将椅座调至适应其高度,使坐垫适当地承托其大腿,同事双脚可平放于地面,如此虽长时间坐于椅子工作,亦不影响正常血液循环。

【座位方向】
可随意转动让使用者可轻易地随桌面状况及工作需要转变身体方向而不需扭曲腰部。

【聚酯(PU)棉】
为一种富弹性二长久不变形之最佳坐垫材料,同时因其生产过程采用模具压铸而成,故坐垫可制成符合人体臀部之形状,除可均衡承托体重外,更使椅子外观具现代化设计气息。

【扶手高度】
调校功能可让使用者将扶手调至其合适高度。如此当其手臂休放于扶手面时肩膀亦可同事松弛休息而减轻工作带来之压力。

【头枕高度】
调校功能于一张现代化办公椅渐形重要。使用者可就本身高度体形将头枕调校至适当位置,使其需要后仰小休时,头及颈部将获全方位承托,消除疲劳。

【五爪椅脚及脚轮】
特别着重其承受力,其关键在于生活参应用之原材料而较难从表面作识别。世界确认之标准要求五爪椅脚应承受1400公斤重量压力;二脚轮则应通过>15N之滚动摩擦阻力测试。
