Description

一种座椅构造a seat structure

技术领域 technical field

本实用新型涉及一种座椅构造,主要指一种使用者由乘坐姿势调整至躺靠姿势时身体主要重量可位于椅背上以提升躺靠舒适性,并可具较佳支撑稳定性。 The utility model relates to a seat structure, which mainly refers to a kind of body weight that can be placed on the back of the chair when the user adjusts from a sitting position to a reclining position, so as to improve reclining comfort and have better support stability.

背景技术 Background technique

习知座椅为提升乘坐舒适性系具有椅背可调整后仰设计,如图9所示为习知结构之一,主要具基座1’、椅座2’、椅背3’,并该基座1’上方及中央分别固设扶手架11’、导杆12’;又椅座2’前方设置可套接导杆12’之滑套21’,又于椅座2’后端设置枢接部22’;又椅背3’于底端设置枢接部31’与椅座2’之枢接部21’枢接,又于中央设置枢接部32’与基座1’上方之扶手架11’后端枢接,使得可令椅背3’、椅座2’具角度较小之乘坐角度,又可令椅背3’后仰,并同时带动椅座2’前移,并使滑套21’可位移至导杆12’前方位置,使得可调整至椅背3’、椅座2’具较大躺靠角度。 In order to improve the ride comfort, the known seat has an adjustable reclining design of the seat back. As shown in Figure 9, it is one of the known structures. It mainly has a base 1', a seat seat 2', and a seat back 3'. An armrest frame 11' and a guide rod 12' are respectively fixed above and in the center of the base 1'; a sliding sleeve 21' which can be nested with the guide rod 12' is arranged in front of the seat 2', and a pivot is arranged at the rear end of the seat 2'. The connecting part 22'; and the chair back 3' is provided with a pivoting part 31' at the bottom end to be pivotally connected with the pivoting part 21' of the seat 2', and a pivoting part 32' is set in the center and the armrest above the base 1' The rear end of the frame 11' is pivotally connected, so that the seat back 3' and the seat seat 2' can have a smaller riding angle, and the seat back 3' can be reclined, and at the same time drive the seat seat 2' to move forward, and make the chair seat 2' move forward. The sliding sleeve 21' can be displaced to a position in front of the guide rod 12', so that the seat back 3' and the seat 2' can be adjusted to have a larger reclining angle.

然而前述结构当躺靠时因椅座2’仅由椅背3’带动前移,该椅座2’前端上扬角度θ1小,造成躺靠时人体大部分重量仍由椅座2’支撑,具舒适性较不理想缺失。 However, when the aforementioned structure is reclined, because the seat 2' is only moved forward by the seat back 3', the upward angle θ1 of the front end of the seat 2' is small, so that most of the weight of the human body is still supported by the seat 2' when reclining, which is very difficult. Comfort is less than ideal missing.

又如图10所示是另一习知座椅结构,主要具基座4’、椅座5’、椅背6’,并该椅座5’前方设置腿靠51’,并于椅座5’设置弹簧52’与基座4’接合,又该椅背6’、椅座5’具固定接合角度,并设置枢接部61’与基座4’枢接,使得乘坐者躺靠椅背6’时可令椅背6’、椅座5’藉由枢接部61’旋转并拉伸弹簧52’以限制椅背6’后仰角度,且因椅座5’对应地面平行方向之仰角θ2可大幅上扬使得使用者大部分躺靠重量可作用于椅背6’上,且可具类似无重力翻转般较佳躺靠舒适性。 Also as shown in Figure 10 is another conventional seat structure, which mainly has a base 4', a seat 5', and a chair back 6', and the seat 5' is provided with a leg rest 51' in front of the seat 5', and the chair seat 5 'A spring 52' is set to engage with the base 4', and the seat back 6' and the seat 5' have a fixed joint angle, and a pivot joint 61' is pivotally connected to the base 4', so that the occupant lies on the seat back When the chair is 6', the chair back 6' and seat 5' can be rotated through the pivot joint 61' and the spring 52' can be stretched to limit the recline angle of the chair back 6', and because the chair seat 5' corresponds to the elevation angle parallel to the ground θ2 can be greatly raised so that most of the user's reclining weight can act on the chair back 6', and it can have better reclining comfort similar to gravity-free flipping.

然而前述设计当椅背6’后仰时该椅座5’系对应向后偏摆,造成重心大幅偏移至基座4’后方位置,导致该整个座椅可能重心不稳而倾倒,又该椅座5’之上扬角度θ2远大于一般人平躺角度,仍造成舒适性不理想缺失。 However, in the aforementioned design, when the seat back 6' is reclined, the seat 5' is correspondingly swayed backward, causing the center of gravity to shift to the position behind the base 4' by a large margin, causing the entire seat to be unstable and topple over. The rising angle θ2 of the seat 5' is much larger than the lying angle of ordinary people, which still causes unsatisfactory lack of comfort.

本实用新型的椅座4上扬时可由顶持片6及滑套55与导杆13接合同时支撑椅座4前端,可具较佳支撑稳定性,又前述椅背2后仰动作令作动架5前移时可拉伸弹性组件8,并可藉由弹性组件8缓冲椅背2后仰力量以具较佳作动顺畅及安全性,且使用者欲令椅背2回复未后仰状态时可藉由弹性组件8之弹性回复力以便于令椅背2回复动作。 When the chair seat 4 of the utility model is lifted up, the top holding piece 6 and the sliding sleeve 55 can be joined with the guide rod 13 to support the front end of the seat seat 4 at the same time, which can have better support stability, and the aforementioned chair back 2 moves back to make the actuating frame 5. When moving forward, the elastic component 8 can be stretched, and the reclining force of the chair back 2 can be buffered by the elastic component 8 so as to have better movement smoothness and safety. The elastic recovery force of the elastic component 8 is used to make the seat back 2 recover.

参图6和图7,如图所示为本实用新型的第二种具体实施方式,其与第一种具体实施方式大致相同,不同之处在于还包括一伸缩杆9,且不设置弹簧,又该基座1下方设置可枢接伸缩杆9一端之第十二枢接部15,并于椅座4前端位置设置可枢接伸缩杆9另一端之第十四枢接部45,又该伸缩杆9由马达连动,使得伸缩杆9收合时可定位椅背2未后仰状态,又如图8所示令伸缩杆9展开时可直接带动椅座4前移,并由椅座4带动作动架5前移、顶持片6展开、椅背2后仰、腿靠7同步展开动作,使得本实用新型可具躺靠舒适及重心平稳安全性功效,又前述结构由伸缩杆9即可强制自动令椅背2后仰或收合动作,可具较佳操作便利性。 Referring to Fig. 6 and Fig. 7, as shown in the figure is the second specific embodiment of the present utility model, which is roughly the same as the first specific embodiment, except that it also includes a telescopic rod 9, and no spring is provided, The twelfth pivot joint 15 that can be pivotally connected to one end of the telescopic rod 9 is set under the base 1, and the fourteenth pivot joint 45 that can pivotally connect the other end of the telescopic rod 9 is arranged at the front end of the seat 4. The telescopic rod 9 is linked by the motor, so that when the telescopic rod 9 is closed, the seat back 2 can be positioned in the unreclined state, and when the telescopic rod 9 is unfolded as shown in Figure 8, it can directly drive the seat 4 to move forward, and the chair seat 4. Drive the moving frame 5 to move forward, the top holding piece 6 to unfold, the back of the chair 2 to lean back, and the leg rest 7 to unfold synchronously, so that the utility model can have the functions of lying comfortably and stabilizing the center of gravity, and the aforementioned structure is composed of a telescopic rod 9 can force and automatically make the chair back 2 recline or retract, which can have better operation convenience.

基于上述描述,本实用新型在椅背后仰动作时可具趋近无重力偏摆舒适性功效,且躺靠时大部分重量作用于椅背上,并椅座可对应前移及上扬动作可具较佳作动稳定性及重心平稳安全性功效,而本本实用新型的腿靠未设置时亦可具本实用新型的诉求功效,又本实用新型的滑套亦可设置为可与导杆锁定之锁定装置(图中未标示)以具更佳定位功效,并前述具体实施方式为本实用新型例示,并非本实用新型限制,凡依据本实用新型精神所为之等效改变亦应属于本实用新型范畴内。 Based on the above description, the utility model can have the effect of approaching gravity-free deflection comfort when the chair is reclined, and most of the weight acts on the back of the chair when reclining, and the seat can be moved forward and raised correspondingly. Better motion stability and stable center of gravity safety effect, and the utility model can also have the appeal effect of the utility model when the leg rest is not installed, and the sliding sleeve of the utility model can also be set to be locked with the guide rod The device (not shown in the figure) has a better positioning effect, and the above-mentioned specific implementation is an example of the utility model, not a limitation of the utility model, and any equivalent changes made according to the spirit of the utility model should also belong to the category of the utility model Inside.
