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.
