Description

椅子 chair

技术领域 FIELD

[0001] 本发明涉及一种椅子,并且具体地,将办公用椅子当作优选对象。 [0001] The present invention relates to a chair, and in particular, office chairs as the preferred object.

背景技术 Background technique

[0002] 对于用户而言,椅子所拥有的第一因素是舒适性。 [0002] For the user, the first factor chairs have is comfort. 具体地,在用于办公室的椅子中,人坐下持续很长时间,并且因此舒适性是重要因素。 Specifically, in the chair for the office, the man sat down last a long time, and thus comfort is an important factor. 存在一些损害舒适性的因素。 There are some factors that damage to comfort. 通常,这样的因素包括因碰撞身体的部分很硬的情形而引起的压迫感和无法容易移动身体的紧张感。 Typically, such factors include oppressive situation due to the collision of hard parts of the body caused by the body and can not be moved easily sense the tension. 因此,采用对抗措施来减轻压迫感和紧张感。 Therefore, the use of countermeasures to reduce tension and oppressive feeling.

[0003] 处理压迫感的问题,使得将垫子布置在座位或靠背中,座位或靠背由网等构成。 [0003] Problem oppressive, such that the mat is arranged in the seat or back, the seat back is made of mesh or the like. 在座位板或靠背板中采用可变形结构在提高柔软度方面也是有效的。 A deformable structure employed in the seat plate or the back plate is also effective in improving softness.

[0004] 另一方面中,为了可以防止或减轻紧张感,在坐下的状态下允许身体移动就足够了。 [0004] On the other hand, in order to prevent or mitigate possible tension, permitting bodily movement in a sitting state is sufficient. 为椅子提供摇摆功能是缓解紧张感的有效手段。 Rocking chair function to provide an effective means to ease the tension. 不过,单独的简单摇摆功能在提高舒适性方面仅具有有限的效果。 However, a separate simple rocking function has only a limited effect in terms of increased comfort. 这是因为,人们在坐下的状态下采取各种姿势,并且因此简单摇摆功能无法跟随人的姿势的变化。 This is because people sit down and take a variety of positions in the state, and therefore can not follow simple swing function changes in people's posture.

[0005]例如,通常就座者扭转身体以便转向一边。 [0005] For example, typically the seat occupant to the torsion body turned to one side. 不过,在靠背具有刚性结构的情况下,当人扭转身体时,与靠背的接触区域减小,使得用户承受压迫感,并且因此,舒适性下降。 However, in the case where the back has a rigid structure, when the human body twisted, the contact region of the backrest is reduced, so that the user withstand pressure, and thus, reduction in comfort.

[0006] 因此,已经针对身体的移动进行设计来提高靠背的跟随性质。 [0006] Accordingly, it has been designed for the movement of the body to increase following the nature of the backrest. 作为这些设计的示例,作为靠背可以通过就座者的体压而变形的结构,文献1至4描述了靠背在三个位置处受到背框架支撑的构造,这三个位置由在上端部中的左右两个位置和下端部的左右中部的位置组成。 As examples of such designs, as may be pressed back by a seated person's body deformed configuration, Documents 1-4 describe the construction of the back frame supported by the back at three positions, the three positions of the upper end portion right and left positions and two positions around the center of the lower end portion of the composition.

[0007] 在靠背通过就座者的体压自由变形的情况下,身体的稳定性下降,因此舒适性相反下降。 [0007] In the case where the seated person by the backrest body pressure free deformation, physical stability decreased, so opposite decrease comfort. 也就是说,靠背必须具有牢固地支撑身体的功能。 In other words, have the backrest must firmly support the body's functions. 具体地,在人坐在椅子上并且进行各种伏案工作的情况下,当人懒散地坐着时,内部器官受挤压,因此强烈的应力作用在身体上。 Specifically, in the case of people sitting on a chair and various desk when people sat idly by, internal organs squeezed, so physically intense stress. 因此,结论是即使在非摇摆状态下,人的身体(尤其是,腰椎)也被支撑并且被保持在背部挺直的状态下的高必要性。 Therefore, the conclusion is that even in the non-swing state, the human body (especially the lumbar spine) is also supported and is held in high necessity under the back straight state.

[0008]当从稳定地支撑身体的这样的功能的角度来观察单独的公众已知的文献时,单独的公众已知的文献的靠背在三个位置处被支撑,这三个位置由在上端处的左右两个位置和下端部的左右中部的位置组成。 [0008] When viewed separately from the literature known to the public such functions to stably support the body angle, public known literature separate backrest is supported at three positions, three positions at an upper end by a two right and left positions at the left and right middle position of the lower end portion of the composition. 因此,结论是避免了过多的变形。 Therefore, the conclusion is to avoid excessive deformation. 不过,由于靠背的下部容易变形,所以预计不具备将身体牢固地支撑在非摇摆状态下并且保持背部挺直的状态的高功能。 However, since the lower portion of the backrest is easily deformed, it is expected that the body does not have to be firmly supported in the swing state and a non-holding state back straight high functionality. 也就是说,在单独的公众已知的文献中,存在稳定地支撑处于非摇摆状态下的身体的不充分功能的可能性。 In other words, in a separate publicly known in the literature, there is stably supported in the possibility of inadequate function of the body in the non-swing states.

[0009] 此外,作为椅子的使用模式,通常在摇摆状态下,身体左右扭动,或替代地,肩膀左右偏离。 [0009] Further, as a mode of use of the chair, generally swing state, the twist around the body, or alternatively, the left and right shoulder deviates. 在这种情况下,负载集中的靠背的上部的左侧或右侧上。 In this case, the upper portion of the left or right side of the load is concentrated on the backrest. 不过,在单独的公众已知的文献中,靠背的上部无法容易地变形。 However, in a separate publicly known literature, the upper portion of the backrest can not be easily deformed. 因此,预计不具备身体的姿势改变的高度跟随性质,并且因此,从该角度看,还存在改进舒适性的空间。 Therefore, we do not have the highly anticipated follow the nature of the body's posture changed, and therefore, from this point of view, there is room for improved comfort.

[0010] 此外,在许多情况下,椅子的靠背被设有由树脂制造的背板。 [0010] Further, in many cases, the chair back is provided with a back sheet made of a resin. 另外,作为用于缓解压迫感以及改进缓冲性质和拟合性质的手段,采用背板具有柔性结构的构造。 Further, as a means for alleviating oppression and improved cushioning properties and fitting properties, the use of the back plate having a configuration of the flexible structure. 例如,在文献5中,本申请的申请人已经公开,在背板中设置在左右方向上水平伸长的大量伸长沟槽,使得身体支撑部分由多级带板组构成。 For example, in Document 5, the present applicant has disclosed, arranged in the horizontal direction of the large elongated horizontally elongated groove in the backplane, so that the body support portion is constituted by a multi-stage band plate group. 在该文献5中,在各个带板中,为了可以容易地发生变形,在左右端部中设有细修整沟槽。 In this document 5, the respective strip, in order to occur can be easily deformed, is provided at the left and right end portions of fine finishing groove.

[0011] 另一方面,文献6公开了具有类似于蜂窝结构的构造的背板。 [0011] On the other hand, Document 6 discloses a configuration similar to the back plate having a honeycomb structure. 此外,文献7公开了如下靠背,在该靠背中,十字形孔和直线形孔规则地布置,使得形成类似于网的结构。 Further, Document 7 discloses a backrest, the backrest, the cross-shaped aperture and rectilinear holes regularly arranged, such that a net like structure.

[0012] 在文献6和7中,靠背的身体支撑部分以网结构形成。 [0012] In Documents 6 and 7, the support body portion formed in a net structure of the backrest. 另外,构成身体支撑部分的一组细线单独地弯曲,并且因此,允许细线根据体压执行伸展变形。 Further, a set of thin wires constituting the support body individually bent portion, and therefore, allows the thin line extending deformable executed according to the body pressure. 因此,整个身体支撑部分可以如此变形为向后凹。 Therefore, the entire body can be so deformed support portion is concave backward.

[0013] 在此处,下面考虑通过靠背实现的支撑身体的功能。 [0013] Here, considered below is supported by the backrest body functions implemented. 单独的高度灵活性是不足够的,并且稳定地支撑身体的功能也是重要的。 The high degree of flexibility alone is not enough, and stably support the body's function is also important. 例如,当存在身体在摇摆状态下抖动的趋势时,在一些情况下,舒适性相反下降。 For example, when there is a tendency body shake in a swing state, in some cases, reverse decline comfort.

[0014] 此外,在就座者在非摇摆状态下执行像PC操作的伏案工作的情况下,当腰椎被牢固地支撑时,背部挺直的适当的姿势被维持,并且因此,该情形是优选的。 [0014] Further, in the case where the sitting at his desk as the PC performs the operation in the non-swing state, when the lumbar spine is firmly supported, back straight the proper posture is maintained, and therefore, this case is preferable of. 相反,当靠背的灵活性过分高时,身体不能稳定地被支撑。 On the contrary, when the flexibility of the backrest too high, the body can not be supported stably.

[0015] 另外,在文献6和7中,采用一种网结构,并且因此,该结构整体上容易变形。 [0015] Further, in Document 6 and 7, it uses a network structure, and therefore, the whole structure is easily deformed. 因此,虽然获得了高缓冲性质,但是结论是在稳定地支撑身体方面存在改进空间。 Thus, while obtaining a high buffering properties, but concluded that there is room for improvement in stable physical aspects of support. 另一方面,文献5的带板不过分执行伸展变形,并且因此,在支撑身体的稳定性方面有优势。 On the other hand, Document strip 5 is excessively performed extensional deformation, and therefore, has an advantage in terms of stability of the support body. 不过,因为在各个带板的伸长上存在限制,所以结论是从灵活性角度来看存在改进空间。 However, because of limitations on the presence of the respective elongated strip, so that the conclusion is room for improvement from the viewpoint of flexibility.

[0028] 技术方案 [0028] Technical Solution

[0029] 本申请由具有层次并且范围拓宽的一组发明构成。 [0029] The present application is constituted by a set hierarchy and the scope of the invention having a broadened. 另外,本申请的典型模式被标识为第一至第十五发明。 Further, the typical pattern of the present application are identified as first to fifteenth invention.

[0030][第一发明] [0030] [First invention]

[0031] 其中第一发明构成上位概念。 [0031] wherein the configuration of the first invention is a broader concept. 第一发明的基本构造包括:座位;靠背;和背框架,所述背框架具有刚性结构且被布置在所述靠背的后方,且在所述背框架与所述靠背之间有间隔。 The basic configuration of the first invention comprises: a seat; back; and a back frame, the back frame having a rigid structure and is disposed rearward of the backrest, between the back and the backrest frame and spaced. 另外,所述靠背由第一支撑装置且由第二支撑装置附接到所述背框架,所述第一支撑装置被布置在靠近所述靠背的上端的高度位置处,所述第二支撑装置被布置在比所述第一支撑装置低且比座位表面高的位置处。 Further, to the backrest and by the first support means by a second support means is attached to the rear frame, said supporting means being disposed at a first height near the upper end of the backrest, said second support means It is disposed at a lower than the first supporting means and a position higher than the seating surface. 此外,所述第一支撑装置被附接到靠近所述靠背中的上端部的左右中部的部分。 Further, the first support means is attached to the left and right middle portion adjacent the upper end of the backrest.

[0032] 在此处,第一支撑装置被附接到靠背的上端或其附近就足够了。 [0032] Here, the first support means is attached to or near the upper end of the backrest is sufficient. 因此,靠背可以在第一支撑装置上跑出。 Thus, the backrest can be run out on the first supporting means. 也就是说,第一支撑装置的附接位置具有竖直宽度。 That is, the attachment position of the first support means having a vertical width. 第二支撑装置是类似的。 Second support means are similar.

[0033] 在本发明中,可以说,靠背在三个位置处被支撑,所述三个位置由上端部的左右中部和上端部下方的左右两个位置组成。 [0033] In the present invention, it can be said, the backrest is supported at three locations, left and right two positions of the three positions around the bottom and upper middle portion of the upper end portion of the composition. 另外,在用户为了执行像PC操作的伏案工作而以不靠在靠背上的状态坐下的情况下,腰椎等可以由在靠背内的在左右两个位置处被支撑的部分稳定地支撑。 Further, in a case where the user PC in order to perform operations as desk and a state not sit down against the back of the lumbar spine can be stably supported by the backrest in two positions at the left and right supported portions. 因此,可以适当地保持背部挺直的状态,并且因此,允许用户采取适当的工作姿势。 Thus, it is possible to appropriately keep your back straight state, and therefore, allows the user to take appropriate working posture.

[0034] 另一方面,第一支撑装置靠近靠背的左右中部,并且因此,靠背的上端部(或上部)跑出到第一支撑装置的在左右方向上的外侧以便构成自由端。 [0034] On the other hand, a first support means close around the middle of the backrest, and therefore, the upper end of the backrest portion (or upper) run out to the outside of the first support means in the horizontal direction so as to form a free end. 也就是说,靠背的上端部(上部)的左右端两者都用作不被从后方支撑的自由端。 That is, both left and right ends of an upper portion of the backrest (upper) are used as the free end of the unsupported from behind. 因此,当采用靠背的上部能够通过体压而变形的构造时,靠背可以变形以便在身体处于靠在靠背上的状态下跟随身体的扭转。 Thus, when a configuration of the upper backrest member can be deformed by pressure, the backrest can be deformed so as to follow the torsion of the body in a state where the body is leaning on the backrest. 这有助于提高倚靠状态下的舒适性。 This helps to improve comfort in leaning state.

[0035][第二发明] [0035] [Second invention]

[0036] 第二发明是第一发明的扩展的示例。 [0036] A second invention is an extended example of the first invention. 在该发明中,所述第一支撑装置具有如下的弹性强度,当就座者的体压作用在所述靠背上时,所述弹性强度允许翘曲变形并由此允许所述靠背的上部向后移动并偏离,而所述第二支撑装置具有的刚度使得,即使当就座者的体压作用时,弯曲变形也基本上不发生,或者替代地,虽然所述就座者的体压引起弹性变形,但是所述第二支撑装置具有的弹性强度使得利用所述弹性强度,所述第二支撑装置的弹性变形的大小低于所述第一支撑装置的弹性变形的大小。 In this invention, the support means having a first elastic strength below, when the upper body of the seated person pressure acts when the backrest on the elastic strength to allow warpage and thereby allow the backrest to after moving to and offset from said second support means having a rigidity such that, even when the body pressure is applied seated person, the bending deformation does not occur substantially, or alternatively, although the seating body pressure cause elastically deformed, but the second supporting means having a strength such that with the spring elastic strength, the magnitude of the elastic deformation of the second support means is less than the size of the elastic deformation of the first support means.

[0037] 在该第二发明中,第一支撑装置具有弹簧性质。 [0037] In the second invention, the first supporting means having a spring property. 因此,在人靠在靠背上的状态下,允许靠背的上部移动以便靠近背框架。 Thus, in a state in man leaning against the backrest, the backrest is moved so as to allow the upper portion close to the back frame. 也就是说,第一支撑装置的反力从后方作用在靠背的上部上,并且因此,该反力向用户提供缓冲作用并且因此提供舒适度。 That is, the reaction force from the rear first supporting means acting on the upper portion of the backrest, and therefore, the reaction force to provide a cushioning effect and therefore provide the user comfort. 此外,第一支撑装置中的变形允许靠背中的扭曲变形,并且因此在人靠在靠背上的状态下,在身体沿右或左方向扭动的情况下,也提高跟随可变形性。 In addition, deformation of the first supporting means allowing the backrest twist deformation, and thus a state in man leaning against the backrest, in the case of twisting of the body along the right or left direction, but also improve the follow deformability.

[0038] 此外,第二支撑装置几乎不因就座者的体压而变形,或替代地,甚至在变形发生的情况下,变形的大小也小于第一支撑装置中的变形的大小。 [0038] In addition, second support means by a seated person is hardly deformed body pressure, or alternatively, even in the case where the deformation occurs, the deformation magnitude smaller than the size of the first support means deformation. 因此,适当地实现了支撑处于倚靠状态下的身体的功能。 Therefore, an appropriate support achieved in the function of the body under the lean state. 此外,当靠背的下部在倚靠的状态(诸如摇摆状态)下过度变形时,身体的稳定性下降,使得在一些情况下,舒适性相反下降。 Further, when the lower portion of the backrest excessive deformation (such as a swing state) in the resting state, physical stability decreased, so that in some cases, decreased comfort contrary. 然而,在第二发明中,甚至在倚靠的状态下,身体也由靠背的下部稳定地支撑,并且因此,身体的过度移动被阻止,使得能够提高舒适性。 However, in the second invention, even in a resting state, the body is stably supported by the lower portion of the backrest, and therefore, excessive movement of the body is prevented, making it possible to improve comfort.

[0039][第三发明] [0039] [Third Embodiment]

[0040] 第三发明是第一发明或第二发明的扩展的示例。 [0040] The third invention is the second example of the invention or extended first invention. 在该发明中,所述第一支撑装置在侧视图中处于在上下方向上伸长的姿势,而所述第二支撑装置被分成左右两个部分,而且左右第二支撑装置在平面图中处于倾斜姿势,使得所述左右第二支撑装置的间隔随着走向较近侧而变宽。 In this invention, the first support means is elongated in the vertical direction in side view a posture, and said second support means is divided into two parts left and right, and left and right second support means is inclined in a plan view posture, so that the interval with the left and right second support means towards the proximal side is widened.

[0041] 在本发明中,第一支撑装置和第二支撑装置可以利用各种模式。 [0041] In the present invention, the first supporting means and second supporting means may be utilized in various modes. 然而,当采用第三发明时,在第一支撑装置和第二支撑装置两者中,在背框架和靠背之间延伸的部分可以具有简单的板形构造。 However, when using a third invention, in both the first support means and second support means, the portion between the back frame and backrest extensions may have a simple plate-shaped configuration. 这提供简要结构的优点。 This provides the advantage of a schematic structure. 此外,第一支撑装置12在上下方向上伸长,并且因此可以通过就座者的体压容易地变形并且向后弯曲。 Further, first supporting means 12 elongated in the vertical direction, and thus can be easily deformed by the pressure of the seated person and the body bent backwards. 因此,可以提高抵抗身体的变化的跟随性质和缓冲性质。 Therefore, it is possible to improve the properties and cushioning properties follow changes in the body's resistance.

[0042][第四发明] [0042] [Fourth Embodiment]

[0043] 第四发明是第一发明或第二发明的扩展的示例。 [0043] The fourth invention is the second example of the invention, or extension of the first invention. 在该发明中,所述背框架包括一对左竖直伸长构件和右竖直伸长构件,这些左竖直伸长构件和右竖直伸长构件倾斜使得随着向上而间隔变窄,并且上端通过联接部分被一体地连接,并且所述第一支撑装置被附接到所述背框架的所述联接部分,并且所述第二支撑装置被附接到所述左竖直伸长构件和所述右竖直伸长构件。 In this invention, the back frame includes a pair of left and right vertically elongated member vertically elongated member, the left and right vertically elongated members such as inclined vertically elongated member is narrowed upward, and the upper end is integrally connected by a coupling portion, and the first support means is attached to the coupling portion of the back frame and the second support means is attached to the left vertical elongated member and the right vertical elongated member. 在此处,针对第四发明的事项也可以适用于第三发明。 Here, for the matter of the fourth invention can also be applied to the third invention.

[0044] 例如,背框架可以由位于靠背的左右中部中的一个构件构造,或替代地,可以利用具有左右竖直部分的倒U形构造。 [0044] For example, the back frame may be configured by one member is located around the middle of the backrest, or alternatively, may utilize an inverted U-shaped configuration having a vertical portion of the right and left. 然而,当采用第四发明构造(倒V形构造)时,获得能够通过采用简单构造来确保高强度的优点。 However, when using the configuration of the fourth invention (the inverted V-shaped configuration), to obtain the advantages of high strength can be ensured by using a simple configuration.

[0045][第五发明] [0045] [Fifth invention]

[0089] 接着,下面参考附图描述本发明的实施例。 [0089] Next, described with reference to the accompanying drawings of embodiments of the present invention. 本实施例适用于在办公室等中广泛使用的转椅。 Suitable for widespread use in offices and the like of the chair according to the present embodiment. 在此处,在下面给出的实施例和权利要求中,术语“向前和向后”以及“左和右”用于识别方向。 Here, in the embodiments given below and the claims, the terms "forward and rearward", and "left and right" used to identify the direction. 然后,参照正常坐在椅子上的人来定义这些方向。 Then, referring to the normal person sitting in the chair to define these directions.

[0090] (1)椅子的轮廓 Outline [0090] (1) chair

[0091] 如图1(A)至2(B)中所示,椅子包括作为主元件的腿装置1、座位2和靠背3。 (B), in [0,091] FIG 1 (A) to 2, a chair leg means includes a main element 1, a seat 2 and a backrest 3. 靠背3被附接到被布置在该靠背3的后方的背框架4。 The backrest 3 is attached to the rear frame is disposed rearward of the backrest 3 4. 腿装置1包括:处于竖直姿势的腿支柱5 ;和中心管6,该中心管6用于支撑腿支柱5。 1 leg apparatus comprising: a leg strut 5 in a vertical posture; and a center tube 6, the central tube 6 for supporting the leg strut 5. 五个分支臂从中心管6在径向方向上延伸。 Five branch arms extending from the central pipe 6 in the radial direction. 然后,将脚轮附接到各个分支臂的末端。 Then, casters attached to the end of the respective branch arms.

[0092] 腿支柱5由设有内筒和外筒的可延伸型的气缸构成。 [0092] The leg 5 is constituted by extendable strut type provided with a cylinder of the inner and outer cylinders. 如图2(B)中所示,将基部7附接到腿支柱5的上端,然后,将背框架4通过接头构件8以允许向后倾斜的方式联接到基部7。 As shown in FIG. 2 (B), the upper end of the leg 7 is attached to the base struts 5 and the back frame 4 by the joint member 8 to allow the inclined rearwardly coupled to the base 7. 在此处,背框架4和接头构件8可以一体。 Here, the back frame 4 and the joint member 8 can be integral. 构成腿支柱5的内筒和外筒可相对自由旋转。 Inner and outer cylinders 5 constitute leg struts can be relatively free to rotate. 因此,基部7 (以及座位2和靠背3)可自由水平旋转。 Thus, the base 7 (as well as the seat 2 and the backrest 3) level of freely rotatable.

[0093] 虽然省略了图示,但是用于弹性地支撑背框架4的向后倾斜的摇动弹簧内置于基部7中。 [0093] Although not illustrated, for elastically supporting the back frame is inclined rearward rocker spring 4 is built in the base 7. 在座位2中,设置在基部7中的中间构件(未示出)以允许绕用作中心的前部向后倾斜和向后移动的方式附接。 The seat 2 provided at the center of the base member 7 (not shown) to allow the front portion around the center of the inclined rearwardly as the rearward movement and attachable. 中间构件和接头构件8以允许相对移动的方式通过在左右方向上水平伸长的轴联接在一起。 The intermediate member 8 and the joint member to permit relative movement of the coupled together by the shaft in the lateral direction horizontally elongated. 凭借此点,与靠背3的向后倾斜联动,座位2执行向后移动和向后倾斜。 With this point, with the backrest inclined rearward linkage 3, the seat 2 moves backward and performing backward tilting.

[0094] 靠背3包括主构件,该主构件由树脂诸如聚丙烯的原材料通过注射成型而制造。 [0094] The backrest 3 includes a main member, the main component of a resin such as polypropylene material is manufactured by injection molding. 在靠背3包括垫子和表皮材料的情况下,需要将靠背3和主构件彼此区别开来。 In the case of a skin material comprising a cushion and a backrest 3, the backrest 3 and the main member needs to be distinguished from each other. 然而,在本实施例中,整个靠背3由主构件构成,并且因此靠背3和主构件的区别不提供实质性优势。 However, in the present embodiment, the entire backrest 3 is constituted by a main member, and thus the difference between the backrest 3 and the main member does not provide substantial advantages. 因此,为了描述简便,不使用术语“主构件”,而使用术语“靠背3”。 Therefore, for simplicity of description, do not use the term "main component", and the term "back 3."

[0095] 靠背3由构成外周的骨架9和位于内部的身体支撑部分10构成。 [0095] The skeleton of the backrest 3 and 9 located inside the outer periphery of the body constituting the support portion 10 is configured. 如图8中所示,骨架9以大致接近四边形的形状形成:一对侧构件9a构成左右两侧;上构件9b在左右方向上水平伸长并且构成上端部;并且下构件9c在左右方向上水平伸长并且构成下端。 As shown, the skeleton 98 substantially close to a quadrangular shape is formed: a pair of side members constituting the right and left sides 9a; 9b horizontal upper member elongated in the lateral direction and forms the upper end portion; and the lower member 9c in the lateral direction and lower elongated horizontal configuration.

[0096] 靠背3的下端被定位成靠近座位表面。 [0096] the lower end of the backrest surface 3 is positioned close to a seat. 在靠背3内,用于支撑就座者的腰椎的腰椎支撑构件11被布置在前面中,且被布置在与就座者的腰椎对应的高度位置处。 3 in the backrest, the lumbar support member for supporting the seat occupant's lumbar spine 11 is disposed in front of, and is arranged at a height position corresponding to the lumbar of the seat occupant. 身体高度和偏好取决于各个就座者。 Height and preferences depend on each person seated. 因此,腰椎支撑构件11是以高度可调节的方式。 Thus, the lumbar support member 11 is height-adjustable manner.

[0097] 本实施例的靠背3具有这样的收缩形状,即,腰椎支撑构件11的附接部分最窄。 [0097] Example 3 of the present embodiment of the backrest has a contracted shape, i.e., the lumbar support member attachment portion 11 is narrowest. 然而,可利用的构造不必限制于此。 However, the configuration may be utilized is not necessarily limited thereto. 也就是说,作为靠背3的构造,可以采用像如下构造的任意形状:在左右方向上的宽度大致固定的构造;上端宽且下端窄的倒置梯形的形状;和上端窄且下端宽的倒置梯形的形状。 That is, as the configuration of the backrest 3, any shape can be constructed as follows: width in the left-right direction is substantially fixed configuration; and the shape of the narrow width of the upper end of an inverted trapezoidal lower; and a narrow upper and lower wide inverted trapezoid shape.

[0098] 例如,如图3⑷和3⑶中所示,背框架4包括左竖直伸长构件和右竖直伸长构件4a,所述左竖直伸长构件和右竖直伸长构件4a倾斜使得它们之间的间隙向上变紧密。 [0098] For example, as shown in FIG 3⑷ and back vertical frame 3⑶ 4 comprises left and right vertically elongated member elongated member 4a, the left and right vertical upright elongated member 4a inclined elongate member such that the gap between them becomes close up. 在左竖直伸长构件和右竖直伸长构件4a中,上端通过联接部分4b —体地连接。 In the left and right vertical upright elongated member elongated member 4a, by coupling the upper end portion 4b - bodies connected.

[0111] (3)腰椎支撑构件 [0111] (3) the lumbar support member

[0112] 接着,下面主要参照图7(A)至图7(C)来描述腰椎支撑构件11。 [0112] Next, following to 7 (C) a lumbar support member 11 will be described mainly with reference to FIG. 7 (A). 腰椎支撑构件11由模制制品构成,模制制品由树脂的原材料制造并且由具有一定弹性的原材料诸如,聚丙烯形成。 Lumbar support member 11 constructed of a molded article, molded articles made from such material and a resin, is formed of a polypropylene material having a certain elasticity. 另外,腰椎支撑构件11具有在左右方向上水平伸长并且横穿靠背3的形状。 Further, the lumbar support member 11 has a horizontal elongated in the lateral direction and the transverse shape of the backrest 3. 在平面图中,腰椎支撑构件11为向前逐渐弯曲的凹形。 In plan view, the lumbar support 11 is gradually curved forwardly concave member. 此外,在竖直截面侧视图中,腰椎支撑构件11为向前略弯曲的凸形。 Further, in a vertical sectional side view, the lumbar support member 11 is convexly curved slightly forward.

[0113] 具有棱柱状并且向后突出的滑动凸台构件34 —体地形成在腰椎支撑构件11的左右两端处。 [0,113] and having prismatic slide rearwardly protruding boss member 34 - are formed at both ends thereof about the lumbar support member 11. 滑动凸台构件34以可自由滑动方式装配到在上下方向上伸长的引导框架部分35中,引导框架部分35设置在靠背3的侧构件9a中。 The boss member 34 to slide freely slidably fitted to the guide frame in the vertical direction of the elongated portion 35, the guide portion 35 provided on the backrest frame side member 3 9a. 如图6(A)和图6(B)所示,引导框架部分35的内周由板部分构成,然后,将上述前侧第二凹部27—体地连接至引导框架部分35的上端。 FIG 6 (A) and 6 (B), the frame inner periphery of the guide portion 35 is constituted by the plate portion, and connecting the second recess to the front side thereof to the guide frame 27- upper end portion 35.

[0114] 如图7(A)至图7(C)所示,具有块形并且设置在钮36中的向前突出部分36a装配到滑动凸台构件34的后端中。 [0114] FIG. 7 (A) to 7 (C), the block-shaped and having a knob 36 provided in the forwardly protruding portion 36a fitted into the rear end of the slide member 34 in the boss. 钮36的向前突出部分36a利用螺栓(未示出)固定到滑动凸台构件34。 Button 36 projecting forward portion 36a with bolts (not shown) fixed to the sliding member 34 boss. 螺母插入沟槽37设置在滑动凸台构件34中。 Nut insertion groove 37 provided on the slide member 34 in the boss. 可以以逐步调节高度的方式来保持腰椎支撑构件11。 Stepwise adjustment may be to keep the height of the lumbar support member 11. 另外,如图6(A)中所示,作为高度调节装置,大量止动孔38设置在引导框架部分35的内板中的大量的竖直阶段处。 Further, as shown in FIG. 6 (A), as the height adjusting means, a large number of stages of the vertical locking of a large number of holes 38 provided in the movable guide plate 35 in the frame portion.

[0115]另外,广泛采用腰椎支撑构件设置在靠背中的构造。 [0115] In addition, widely used in the configuration of the lumbar support member disposed in the backrest. 然而,通常,在许多情况下,腰椎支撑构件布置在垫子的后侧上或布置在网材料的后侧上。 However, in general, in many cases, the lumbar support member is disposed on the rear side of the mat or web is disposed on the rear side of the material. 不过,在垫子或网材料介于腰堆支撑构件与身体之间的情况下,在一些情况下,期望强烈的“抵靠感觉”的人感觉不满意。 However, in the case of a mat or mesh material is interposed between the support member and the waist pile body, in some cases, we expect a strong "against the feeling" of people feeling dissatisfied. 此外,在像靠背未设有垫子或网的情况的一些情况下,腰椎支撑构件需要被布置在背板的近侧上。 Further, in some cases, as the backrest is not provided where the mat or mesh, lumbar support member needs to be arranged proximally on the backplane.

[0116] 作为这种情况的示例,JP-A-2008-237333公开了一种方法,在靠背由框架部分和位于其内侧的背板构成并且在背板中设置大量狭缝的构造中,腰椎支撑构件布置在背板的近侧上。 [0116] As an example of this situation, JP-A-2008-237333 discloses a method, constituting the backrest and arranged in a large number of slits are configured in the backplane by the frame part and positioned inside the backplane, lumbar a support member disposed on the proximal side of the backing plate. 此外,该文献公开了如下构造:从外侧装配到框架部分上的夹型手把被一体地设置在腰椎支撑构件的左右两个端部上,并且因此,框架部分由手把从下方弹性地保持。 Further, this document discloses the following structure: is provided integrally on both right and left end portions of the lumbar support member is fitted to the outside from the handlebar clamp type frame portion, and therefore, the frame portion elastically held from below by the handle .

[0117] 不过,像在上述现有技术专利文献中那样,在从外部将手把装配到框架部分上的构造中,手把跑出框架部分的左右外侧,并且因此,预期会有如下麻烦:人的衣服被卡在手柄中,或替代地,物体抵靠手把,使得手把受损。 [0117] However, as above, in the externally fitted to the handle portion of the frame structure in the above prior art patent literature, ran around the handle portion outside of the frame, and therefore, is expected to have the following problems: 's clothes were stuck in the handle, or alternatively, the object against the handle, such that damage to the handle. 此外,手把仅通过摩擦维持高度,并且因此,出现如下可能性,即,腰椎支撑构件通过就座者的体压而滑动(诸如,上升或下降)。 In addition, the handle height is maintained only by friction, and therefore, there is a possibility that the seat occupant lumbar support member by the sliding body pressure (such as a rising or falling).

[0118] 相反,在本实施例中,设置在腰椎支撑构件11的左右两个端部中的滑动凸台34贯通骨架9的引导框架部分35。 Slide projection [0118] In contrast, in the present embodiment, is provided at left and right ends of the lumbar support member 11 in the frame 34 through the guide portion 35 of the bobbin 9. 因此,钮36可以被布置成不从骨架9的左右外侧跑出。 Thus, knob 36 may be arranged so as not to escape from the left and right outer skeleton 9. 凭借此点,衣服被卡在钮36中或替代地物体抵靠钮36的情形可以避免,或替代地受到显著抑制。 With this point, the clothes were stuck in the button object 36 or alternatively against the knob case 36 can be avoided, or alternatively significantly inhibited. 此外,容易提供由止动孔38构造的高度保持装置以用于引导框架部分35的高度调节。 In addition, readily provide a highly hole 38 configured by the stopper holding means for guiding the frame part 35 of the height adjustment. 因此,腰椎支撑构件11可以以不允许偏离移动的方式被保持在期望的高度处。 Thus, the lumbar support member 11 may be held at a desired height is not allowed to deviate from a movable manner.

[0119] 在此处,高度调节装置可以利用各种构造。 [0119] Here, the height adjustment means may be utilized in various configurations. 在像在该实施例中在引导框架部分35中设置止动孔38的情况下,配合到引导框架部分35和从引导框架部分35拆卸的弹性构件被设置在钮36的块形向前突出部分中就足够了。 In the case of this embodiment, as in the guide frame portion 35 is provided in the stopper hole 38, the frame portion 35 fitted to the guide frame and the elastic member from the guide portion 35 is detachably provided at the block-shaped knob portion 36 projecting forwardly it is sufficient. 引导框架部分35具有一定量的向前和向后宽度,并且因此,滑动凸台构件34的贯通不引起强度下降。 Guide frame portion 35 has a certain amount of width in forward and backward, and therefore, the slide through boss member 34 does not cause a strength decrease. 钮36可以以简单的板形制造,然后,可以将钮36螺接到滑动凸台构件34。 Button 36 may be manufactured in a simple plate shape, and then, the button 36 may be screwed to the boss member 34 slidably.

[0120] (4)靠背的结构 [0120] (4) the structure of the backrest

[0121] 接着,在靠背3内,以下主要参照图8至图10描述身体支撑部分10的结构的细节。 [0121] Next, in the backrest 3, the following main 8 to 10 the details of construction of the body support portion 10 described with reference to FIG. 如图8中所示,在本实施例中,身体支撑部分10包括:水平伸长的侧撑条40组,该侧撑条40被连接到左右侧构件9a ;和一组水平伸长的中央撑条41,该中央撑条41位于侧撑条40组之间。 As shown, in this embodiment, the body 10 includes a support portion 8 in which: a horizontally elongated side stay 40 group, the side stay 40 is connected to the left and right side members. 9A; and a group of horizontally elongated central stay 41, the stay 41 is located in the center between the side stay strip 40 groups. 撑条40和41组两者都被布置在上下偏离的状态下。 Both struts 40 and 41 are set in a state arranged vertically offset. 中央区域由中央撑条41组构造,并且侧区域由侧撑条40组构造。 The central region by the central bracing structure 41 groups, and the side region 40 of the side stay group configuration.

[0122] 另外,在左右方向上相邻的中央撑条41的左右端和侧撑条40的末端通过联接件(接头撑条)42 —体地连接。 [0122] Further, in the lateral direction adjacent to the central strut 41 and the left and right ends of the end strip side stay 40 by a coupling member (joint struts) 42-- linker ground. 在这种情况下,在左右方向上,在侧撑条40的末端与中央撑条41的端部之间存在微小间隙。 In this case, in the lateral direction, at the end of the side stand bar 40 and the central strut there is a slight gap between the ends of the bar 41. 因此,联接件(接头撑条)42在前视图中处于倾斜姿势。 Thus, the coupling member (joint struts) 42 is in the inclined posture in the front view. 此外,中央撑条41和侧撑条40以上下偏离的方式布置,并且因此,在上下方向上相邻的联接件(接头撑条)42处于相反取向的姿势中。 In addition, the central strut 41 and the side stays 40 above embodiment the strips are arranged offset, and thus, in the vertical direction of the adjacent coupling member (joint struts) 42 is oppositely oriented posture. 此外,在上下方向上相邻的联接件(接头撑条)42的基部和撑条40和41 一体地连接。 Further, in vertically adjacent coupling elements (struts linker) and the base portion 42 of the stay 40 and 41 are integrally connected. 因此,联接件(接头撑条)42组在前视图中具有Z字形。 Thus, the coupling member (joint struts) 42 having a group Z-shape in a front view.

[0123] 靠背3收缩,使得靠近下侧的部分在前视图中变窄。 [0123] shrink back 3, such that the narrowed portion near the lower side in the front view. 因此,向外弯曲的凹形形状与靠背3的侧构件9a—起形成。 Thus, the outwardly curved concave shape of the back side member 3 is formed from 9a-. 此外,联接件(接头撑条)42在前视图中也是向外弯曲的凹形以便跟随侧构件9a的形状。 In addition, the coupling member (joint struts) 42 is a front view of a concave curved outwardly so as to follow the shape of the side member 9a. 此外,侧构件9a和中央撑条41在左右方向上具有大致相同的长度。 In addition, the side member 9a and a central stay 41 having substantially the same length in the lateral direction.

[0124] 侧撑条40和中央撑条41具有板形结构,其前后面是宽的。 [0124] side stay 40 and the stay 41 has a central plate-shaped structure, which is wide front and rear. 然而,如图10中所示,肋43在侧撑条40的后面和中央撑条41的后面中一体地设置。 However, as shown in FIG. 10, the central rib 43 and the rear support bar 40 is integrally provided in the rear stays 41 of the side bar. 因此,侧撑条40的截面和中央撑条41的截面具有侧T形。 Thus, the central section and the side stay 40 stay bar 41 has a cross-sectional side T-shaped. 肋43的后面与联接件(接头撑条)42的后面在同一平面内。 Behind the rib 43 of the coupling member (joint struts) 42 back in the same plane. 联接件(接头撑条)42具有细带板的外观,并且因此,可以容易地变形,使得侧V的角度变宽或变窄。 The coupling member (joint struts) having the appearance of a fine strip 42, and thus, can be easily deformed, such that the angle of the V-side widened or narrowed. 也就是说,在腰椎支撑构件111中,撑条140和141的密度是高的。 That is, the lumbar support member 111, struts 140 and 141 density is high. 凭借此点,腰椎支撑部分比其它部分具有更高的刚度。 With this regard, the lumbar support portion having a higher stiffness than other portions.

[0125] 侧撑条40组和中央撑条41组被布置在大量竖直阶段处。 [0125] side stay 40 and the central set of strut 41 is disposed in a large group of the vertical stage. 因此,在左右方向上水平伸长的空间44分别在上下方向上相邻的侧撑条40之间以及中央撑条41之间是空的。 Thus, the horizontal spaces 44 are elongated in the vertical direction adjacent in the lateral direction between the side stay and the central bar 40 between the struts 41 is empty. 另夕卜,在本实施例中,除了腰椎支撑部分之外,空间44的竖直宽度尺寸是撑条40或41的竖直宽度的2倍等。 Another Bu Xi, in the present embodiment, in addition to the lumbar support portion, the vertical width dimension of the space 44 is twice the width of the other vertical stay 40 or 41. 在腰堆支撑部分中,空间44的竖直宽度尺寸大致被设置为与撑条40或41的竖直宽度相同的水平。 Lumbar support portion in the stack, the vertical width dimension of the space 44 is provided with approximately the width of vertical strut 40 or 41 to the same level. 因此,腰椎支撑部分具有较高的刚度。 Thus, the lumbar support portion has high rigidity.

[0126] 从一开始,侧撑条40和中央撑条41的竖直宽度和节距(密度)可以被任意地设置。 [0126] From the beginning, the side stay 40 and the width and pitch of the central vertical strut (density) can be arbitrarily set to 41 bar. 例如,撑条40或41和空间44的竖直宽度尺寸可以被设置成在上下方向上整体处于大致相同的水平。 For example, the stay 40 or 41 and the vertical width dimension of the space 44 may be provided integrally in the vertical direction at substantially the same level. 替代地,撑条40或41的竖直宽度尺寸可以被设置成在整体上小于空间44的竖直宽度尺寸。 Alternatively, stay 40 or 41 may be provided in the vertical width dimension smaller than the vertical width dimension of the space 44 as a whole.

[0127] 此外在本实施例中,身体支撑部分10已经由两排侧撑条40和一排中央撑条41构造。 [0127] Further, in the present embodiment, the body is supported by the support portion 10 has two rows of side panels 40 and a row of central strut 41 is configured. 然而,可利用的构造不必限制于此。 However, the configuration may be utilized is not necessarily limited thereto. 也就是说,可以不设置中央撑条41,并且因此,身体支撑部分10可以由左右侧撑条40以及由用于连接该左右侧撑条40撑条的一个联接件(一个接头撑条)42构造。 That is, the center may not be provided a stay 41, and thus, the support portion 10 of the body 40 may stay left and right sides and a coupling member of the left and right side stay 40 for connecting stay from (a joint struts) 42 structure. 替代地,身体支撑部分10可以由两排侧撑条40和位于该侧撑条40之间的两排中间撑条构造。 Alternatively, the body may support portion 10 is supported by two rows of side panels 40 and the side stays positioned intermediate between the two rows of strips 40 stay construction. 在设置两排中间撑条的情况下,三个联接件(三个接头撑条)42是必要的。 In the case where two rows of intermediate stays, three coupling members (three joints stay) 42 is necessary. 此外,身体支撑部分10可以由五排撑条组构造,五排撑条组由两排侧撑条40、一排中央撑条41和两排中间撑条构成。 Further, the support portion of the body 10 may be formed of five rows of struts configured group, the group consisting of five rows of two rows of struts side stay 40, a row of central strut 41 and intermediate strut constituting two rows. 此外,靠背3可以利用其它构造。 In addition, other configurations may be utilized backrest 3.

[0128] (5)总结 [0128] (5) Summary

[0129] 接着,下面参照图11来描述操作。 [0129] Next, the operation will be described below with reference to FIG 11. 首先,下面描述摇摆状态。 First, the following describes swing state.

[0130]例如,在摇摆状态下就座者的体压从前方作用在靠背3上,如由箭头F所指示。 [0130] For example, in the swing state of the seat occupant from the front of the body pressure acting on the backrest 3, as indicated by the arrows F. 另夕卜,作用在靠背3上的负载由第一支撑装置12和第二支撑装置13支撑。 Another Bu Xi, the load acting on the backrest 3 is supported by the first supporting means 12 and second support means 13. 另外,如由箭头Y的指示,第一支撑装置12可以执行弯曲变形,使得上端在侧视图中通过来自前方的负载而向后移动。 Further, as indicated by the arrow Y, the first supporting means 12 may perform the bending deformation, so that the upper end is moved rearward by a load from the front in a side view. 另一方面,如由箭头X所指示,第二支撑装置13可以执行弯曲变形,使得末端在平面图中向后移动。 On the other hand, as indicated by an arrow X, a second supporting means 13 may perform the bending deformation, so that the backward movement of the end in a plan view. 然而,由于第二支撑装置13具有高刚度,所以靠背3的背框架4由第二支撑装置13牢固地保持,并且因此就座者的腰椎以令人满意的稳定性被保持。 However, since the second support means 13 having a high rigidity, so that the backrest 3 of the rear frame 413 is securely held by a second support means, and thus the lumbar seat occupant is maintained at a satisfactory stability.

[0131] 另一方面,由摇摆引起的力矩在很大程度上作用在靠背3中的上端部上。 [0131] On the other hand, the moment caused by the swinging action to a large extent in the upper portion of the backrest 3. 然而,第一支撑装置12具有比第二支撑装置13低的刚度,并且因此容易地根据体压执行翘曲变形。 However, the support means 12 having a first 13 lower than the second stiffness support means, and thus easily deformed according to the body pressure warping executed. 因此,在摇摆时,靠背3可以执行翘曲变形,使得靠背3的上端部靠近背框架4的上端部。 Accordingly, when the swing, the backrest 3 can be performed warpage, so that an upper portion of the backrest portion 3 close to the upper end of the rear frame 4. 靠背3的该翘曲变形可以提高在摇摆时的缓冲性质。 The warpage of the backrest 3 can be increased when the swing buffering properties.

[0132] 此外,在摇摆状态下,当人沿右或左方向扭动上半身或替代地使肩部沿右或左方向移位时,构成第一支撑装置12的两个左右弹簧部分12a不均匀地执行弯曲变形,使得靠背3可以变形并且扭曲以便跟随身体的扭动或移位。 Two right and left portions of the spring [0132] Further, in the swing state, when the person in the upper right or left twisting direction, or alternatively that the shoulder is displaced in right or left direction, the first supporting means 12 constituting the unevenness 12a performing bending deformation, so that the backrest 3 can be deformed and twisted so as to follow displacement or twisting of the body. 因此,靠背3可以跟随身体的姿势的改变。 Therefore, the backrest 3 can follow the change the posture of the body. 结果,舒适性可以提高。 As a result, comfort can be improved.

[0133] 如从图11可以清晰地看到的,靠背3在平面中是逐渐向前弯曲的凹形。 [0133] As can be clearly seen from FIG. 11, the backrest 3 is gradually curved forwardly concave in a plane. 弯曲的程度在腰椎支撑构件11的附近最大,而上端部处于几乎平坦的状态下。 The maximum degree of bending of the support member 11 in the vicinity of the lumbar spine, the upper part is almost flat. 因此,在腰椎被保持诸如不向右或向左偏离的状态下,肩部(或靠近肩部的部分)可以容易地左右移位。 Thus, in the lumbar spine to be held as not to deviate to the right or left state, the shoulder (or near the shoulder portion) of the left and right can be easily displaced. 另外,从这点来看,可以获得高舒适性。 In addition, from this point of view, a high comfort.

[0134] 如图2(B)中所示,在就座者不靠在靠背3上的中性状态下,靠背3呈现略向后倾斜的姿势,并且腰椎支撑构件11位于最前侧上。 As shown in [0134] FIG. 2 (B), in the neutral state does not seated against the backrest 3, the backrest 3 presents a slightly rearwardly inclined posture, and the lumbar support member 11 is located on the most front side. 另外,当用户执行诸如PC操作的伏案工作时,用户采取腰椎抵靠靠背3的腰椎支撑构件11的姿势。 Further, when the user performs the operation desk work such as a PC, the user takes the posture of the lumbar back against the lumbar support member 11 3. 然而,由于第二支撑装置13具有高刚度,所以靠背3不执行与处于中性状态下的就座者的体压相关联的翘曲变形,并且因此,人的腰椎由靠背3以令人满意的稳定性支撑。 However, since the second support means 13 having a high rigidity, so that the backrest 3 is not performed and the associated warping sitting person in a neutral state of the body pressure, and therefore, the backrest 3 by a human lumbar satisfactory the stability of the support. 因此,用户的上半身不会变得不稳定并且被保持在背部挺直的优选姿势中。 Accordingly, the upper body of the user does not become unstable and is preferably held in the upright posture of the back. 因此,本构造在中性状态(非摇摆状态)下的姿势维持功能方面也有优势。 Therefore, the construction posture in a neutral state (non-swing states) also has the function of maintaining the advantages.

[0135] 因为侧撑条40和中央撑条41上下偏离,并且联接件(接头撑条)42具有Z字形构造,所以本实施例的靠背3可以执行翘曲变形,使得身体支撑部分10根据就座者的体压向后隆起。 [0135] Since the side stay 40 and the stay 41 vertically offset from the center, and the coupling member (joint struts) 42 having a Z-shaped configuration, the backrest 3 of the present embodiment may be performed warpage, so that the support portion 10 on the body seat body pressure uplift backward. 因此,本构造在与用户身体的拟合性质方面有优势并且在身体移动的跟随性质方面也有优势。 Therefore, this structure has an advantage in terms of the nature of the user's body fit and follow the nature of body movement also has the advantage.

[0136] 此外,当在上下方向上相邻的联接件(接头撑条)42变形使得相互张角(V的角度)变小时,出现中央撑条41向后偏离的趋势。 [0136] Further, when vertically adjacent coupling member (joint struts) 42 deform such that each opening angle (the angle of the V) becomes small, central tendency stays 41 rearwardly offset occurs. 结果,身体支撑部分10变形从而向后隆起。 As a result, the support body portion 10 is deformed to bulge backward. 这提高了对用户身体的缓冲和拟合性质。 This improves the fit and cushioning properties of the user's body.

[0137] 本申请基于2013年6月6日提交的美国临时专利申请(61/831,763),该临时申请的内容通过引用并入本文。 [0137] The present application is based on US provisional patent application (61 / 831,763) June 6, 2013 submitted by the contents of which are incorporated herein by reference.
