[0030] 如图2所示,功能架处于坐状态;当直线推杆电机22通过左右连接杆21推动两个连杆Dll向前转动时,搁腿板的两个四连杆机构动作,直至搁腿板至抬起状态时,如图3所示,连杆Dll受限位柱限位使其与坐垫连接架12连为一体,这样直线推杆电机22向前的驱动力就直接施加在坐垫连接架12上,驱动坐垫连接架12向前移动,坐垫连接架12与底座20之间形成四连杆机构,这样坐垫连接架12及其上坐垫呈向前向上的摆动抬升过程,同时,因为与连杆K18铰接的连杆117经由连杆H15、连杆G14与底座20连接,并且连杆H15的中间与坐垫连接架12的上方后部铰接,所以,在坐垫连接架12的向前移动过程中,坐垫连接架12后部的安装靠背的四连杆机构(坐垫连接架12、连杆J16、连杆K18和靠背连接件19构成四连杆机构)也产生变化,促使靠背向前移动并逐渐倾倒,直至躺状态,如图4所 [0030] As shown, the seat 2 is in a state holder function; when the linear motor 22 via the push rod about a connecting rod 21 pushed forward rotation Dll two links, two four-link mechanism is operated leg rest panel, until when leg rest panel to raised state, shown in Figure 3, the restricted link Dll stop bit column connecting it with the seat cushion frame 12 as a single entity, so that the driving force of the forward jacks 22 is applied directly to the motor connected to the seat cushion frame 12, the drive moves forward the seat cushion frame 12 are connected to form a four-bar linkage between the seat cushion 12 is connected with the base frame 20, so that the seat cushion and the seat cushion frame 12 is connected as a forward swing upward lifting process, at the same time, since the link rod articulated K18 H15 117 via the link, the link 20 is connected to the base G14, H15 and intermediate link connecting the seat cushion and the rear upper hinge frame 12, the connecting frame 12 forwardly of the seat cushion movement, the backrest mounting the rear cushion 12 connected to the four bar linkage frame (seat cushion frame 12 is connected, links J16, K18 rod connecting member 19 and the back constituting the four-bar linkage) is also a difference, causes the backrest forward and poured gradually moved until the lying state, as shown in FIG 4 . 反之,直线推杆电机22复位过程中,坐垫连接架12先后移,靠背逐渐竖起,然后搁腿板放下。 On the contrary, the linear motor 22 during reset push rod, connected to the seat cushion frame 12 has shifted back gradually erected and put down the leg rest.

[0031] 实施例2: [0031] Example 2:

[0032] 如图6所示的一种靠背安装结构,与实施例1的不同仅在于:连杆J16的中间与连杆117的一端铰接,连杆117的另一端与连杆H15的上端铰接,连杆H15的中间与坐垫连接架12的上方后部铰接,连杆H15的下端与连杆G14的一端铰接,连杆G14的另一端与底座20铰接,这样,坐垫连接架12、连杆H15、连杆117和连杆J16构成四连杆机构,其他与实施例I相同。 One kind of the backrest shown in [0032] mounting structure 6, different from Example 1 only in that: one end of the intermediate link J16 and the link 117 is hinged, the other end of the link 117 and the upper end of the connecting rod articulated H15 , H15 intermediate link connected with the upper rear portion of the seat cushion frame 12 of the hinge, the lower end of the link rod H15 hinged at one end of the G14, G14 link the other end of the hinge base 20, so that the seat cushion frame 12 is connected, the connecting rod H15, J16 and a link rod 117 constitute a four-bar linkage, the other same as in Example I. 其动作原理和过程也与实施例1相近。 Its principle of operation and the process is similar to Example 1.

[0033] 本发明中,提供动力的驱动装置只有一个,搁腿板安装在两个相互联系的四连杆机构上,通过动力驱动装置驱动两个四连杆机构联动,从而实现搁腿板在抬起状态和放下状态之间的转换,并且在这个转换过程中,搁腿板与坐垫之间的距离变化很小,避免了搁腿板搓拉裤腿,提高了使用舒适性。 [0033] In the present invention, the drive means powered only one, the leg plate is mounted on four-bar linkage of two interconnected, means for driving two four-bar linkage driven by the power linkage, thereby achieving the leg plate lifted and lowered state transitions between the states, and in this conversion process, the distance between the leg rest and the seat plate change is very small, to avoid rubbing pull the leg plate legs, to improve the comfort of use. 当搁腿板至抬起状态时,通过限位结构A使得搁腿板的两个四连杆机构与坐垫连接架连为一体,这样驱动装置的向前驱动力就施加在坐垫连接架上,驱动坐垫连接架向前移动,坐垫连接架与底座之间形成四连杆机构,这样坐垫连接架及其上坐垫呈向前向上的摆动抬升过程,同时,因为与连杆K或者连杆J铰接的连杆I经由连杆H、连杆G与底座连接,并且连杆H的中间与坐垫连接架的上方后部铰接,所以,在坐垫连接架的向前移动过程中,坐垫连接架后部的安装靠背的四连杆机构(坐垫连接架、连杆J、连杆K和靠背连接件构成四连杆机构)也产生变化,促使靠背向前移动并逐渐倾倒,实现了坐垫和靠背的联动,避免了腰部衣物的搓拉,提高了使用舒适性,并且,本方案结构还实现了靠墙倾倒,即座椅在端坐状态时即使靠背靠墙,也仍旧可以直接实现躺倒动作, When leg rest panel to raised state, the retaining structure such that the two four-bar linkage A and the seat leg rest frame board is connected as a single entity, the forward driving force is applied to such a driving device is connected to the seat frame, connecting the seat cushion frame is moved forward drive, four-bar linkage is formed between the seat cushion frame and connected to the base, so that the seat cushion and the seat cushion frame connected to the forward direction as a pivoting lifting process, at the same time, because the link rod K or J hinge H I link via the link, the link connected to the base G, and H of the intermediate link connected to the upper rear portion of the seat cushion frame hinge, therefore, the process of connecting the seat cushion frame forward movement, the rear portion of the seat cushion frame connector the four bar linkage mounting the backrest (seat cushion frame is connected, link J, K, and the link connecting the back member constituting the four-link mechanism) is also a difference, causes the backrest is moved forward and gradually poured to achieve the cushion and backrest linkage , to avoid rubbing the waist to pull the laundry, improving the comfort of use, and the structure of the present embodiment also enables the wall dumped, i.e. when sitting in the seat backrest wall even state, can still be achieved lying direct action, 现有技术中,都需要座椅的靠背与墙之间留有一段距离以实施躺倒动作,因而本方案结构更加方便使用和节约空间。 In the prior art, between the backrest and the need to leave a distance to the wall of the seat reclining operation of embodiment, and therefore the structure of the present embodiment is more convenient to use and space-saving.
