A frame body structure of elastic arcuate cushion

Abstract: The frame body structure of elastic arcuate cushion according to the present invention is characterized by the following: the frame body structure of said cushion consists of two sets of corresponding frame plates up and down and left and right moulded integrally, the said two sets of corresponding frame plates are shaped to meet with the arcuate human body, the central part surrounded by the said two-set frame plates is hollow but not plane, and the surface of said two-set frame plates is provided with a plurality of longitudinal or transverse guide holes for knitting the cushion body with beads or other textiles in the scope of said central part so that the knitted cushion with a full elasticity and an elevational shaping and curve can meet with the arcuate human body and the user can feel comfortable when he sits and leans on the cushion.

Description: Car seats are, in general, provided with seat and back cushions for the users' sitting and leaning thereon so that they feel soft and comfortable but the feeling of these comfortable cushions chiefly depends on the status of back cushion coinciding with the human body spine when the back cushion contacts the human body spine. Since the human body spine supports the whole weight of human body and head, if one's spine is in a poor state of bending for a long time, he will feel lumbago, back pain and sore head and neck, and the body is very uncomfortable. The conventional cushion (such as the back cushion) is composed of a piece of soft sponge adhered onto a piece of fixed hard plate. So far as this fixed cushion is concerned, when the human body spine leans thereon, the spine will always have to meet with its established fixed pattern, and will be subject to the restraint of said pattern, so the user's spine will feel uncomfortable and his health will be unfavourably affected (such as suffering herniation of interverbral disc), such back cushion is really alien to the design of human body engineering. In addition, the plate surface of conventional cushion (such as back cushion) is a flat plate without any arcuate shaping, so when one's body leans on the flat plate cushion, the arcuate part of his spine cannot coincide with the said plate surface, and his spine cannot be supported. Therefore, so far as those who have to stay in the car for a long time are concerned, it is very uncomfortable; particularly where the plate surface of conventional cushion is airtight, the user's back tends to sweat and he will be tired of leaning his back thereon for a long time, it is also detrimental to the human body health. Furthermore, the conventional cushion (such as the back cushion) is a fixed cushion body with fixed plate, so when persons with different physiques lean thereon, they feel differently about their weights acting on the position of cushion and applying force thereto. Since the suitable position of conventional cushion cannot be optionally adjusted up and down and left and right, the conventional cushion may be applied to the people with normal physique only but cannot be applied to various persons including the adult, children, men and women, this is also a common drawback of conventional cushion FR-1130816 discloses a car seat including a frame structure and a cushion body woven inside the frame body, the frame body consisting of a set of upper and lower frame sections and a set of left and right frame sections which are symmetrical relative to each other and are curved in such a manner as to correspond to an arcuate part of a human body. A frame body structure of an elastic arcuate cushion according to the present invention consist of a frame body and a cushion body knitted inside the frame body, said frame body consisting of a set of upper and lower frame sections, and a set of left and right frame sections which are symmetrical relative to each other and which are curved in such a manner as to correspond to an arcuate part of a human body. The frame body is integrally moulded and defines a non-planar central region within the frame sections, and each frame section includes a plurality of longitudinal and outwardly tapering transverse guide holes through which the cushion body is knitted. The cushion body is formed by beads or other textile material in the non-planar central region, the knitted cushion body conforming to the shape and curvature of the arcuate part of the human body, the elasticity of the arcuate cushion enabling it to adapt to different positions assumed by the arcuate part of the human body so as to be comfortable for a user. The cushion may have a hollow air-tightness and an elasticity which conforms with the shape of the human body.

DETAILED DESCRIPTION As shown in Figs. 1 and 2, the frame body (10) consists of a set of upper and lower frame sections (10A) and another set of left and right frame sections (10B). These upper and lower frame sections (10A) and left and right frame sections (10B) are symmetrical relative to each other. As shown in Fig 2-1 and 2-2, these two sets of frame sections have a curve meeting with the arcuate human body (such as the spine, cervical spine and waist), and the central part surrounded by the said two sets of frame sections (10A), (10B) forms a non-planar hollow part (M). As shown in Figs, 2, 2-1, 2-2, 2-3 and 2-4, a plurality of longitudinal guide holes (11) and transverse guide holes (12) are provided to each frame section of frame body (10) in the vertical and horizontal directions of the surface of said section respectively, and through these holes, the following tenacious thread can thread beads or various cloth (such as jean (denim), synthetic leather, non-woven cloth or network cloth) to finish an integral cushion (such as back cushion, waist-protecting cushion or pillow cushion) to be used by the user. As shown in Fig. 2-4, the said transverse guide hole (12) is outward tapered so that the tenacious thread tends to pass through it and the assembly of cushion can be more effective. As shown in Figs. 2-5 and 2, two outward tapered through holes (13) are separately provided to the surface of said frame plate (10A) to accomodate a toggle (14), and a clip 15 is provided t fix the said cushion onto the pillow of seat in the car ad to adjust the position of said cushion up and down. When to assemble the frame body (10) to be an integral cushion, the examples of beaded cushion 100 as shown in Figs. 3, 4 and 5 may be followed. The process of knitting the beaded cushion (100) is so: firstly to insert the two terminals La and Lb of two tenacious threads L in the position N1 of the first transverse guide hole (12) of the upper frame section (10A), then to dispose the required beads (16) on these two terminals La and Lb, and then to let these two terminals La and Lb pass out from the position S1 of the first transverse guide hole of the lower frame section (10A) to finish the knitting of the first series of longitudinal beads; then to insert the said two terminals La and Lb in the position S2 of the second transverse guide hole of the lower frame section (10B), to dispose the beads (16) with equal number on these two terminals La and Lb, to let these two terminals La and Lb pass out from the position N2 of the second transverse guide hole of the upper frame section 10A to finish the longitudinal knitting of the second series of beads; and in such a sequence, to insert these two terminals La and Lb in the positions S3, S4, N4, ... Nn, Sn from the positions N3, S3, S4, ... Nn-1, Nn, and meantime, during the threading, the required beads are disposed on these two terminals La and Lb one after another so as to finish the longitudinal knitting of beaded cushion (100). As shown in Figs. 3, 4 and 5, when the longitudinal knitting of beaded cushion (100) is finished, the two terminals La and Lb may be inserted in the position E1 of the first transverse guide hole (12) of right frame section (10B), then to dispose a bead (16) on these two terminals La and Lb and to thread the beads in the longitudinal direction in the manner of "crossing pinching", then a bead is disposed on these two terminals La and Lb which thread the next series of beads in the longitudinal direction in the same manner of "crossing pinching", and in such a sequence, the transverse knitting of the first series of beads is finished; thus, where longitudinal and transverse threads cross, the pair of threads passing in one direction pass between the two threads running in the other direction; then to let these two terminals La and Lb pass out from the position W1 of the first transverse guide hole of left frame section (10B) and insert in the position W2 of the second transverse guide hole to proceed with the knitting of the second series of beads in the transverse direction; and in such a sequence, to insert these two terminals La and Lb in the positions E2, E3, W3, W4, ... En, Wn from the positions W2, E2, E3, W3, ... En-1, Wn, and finally, to tie down these two terminals La and Lb so as to finish the knitting of beaded cushion (100); So far as the finished beaded cushion is concerned, the two terminals La and Lb for tranverse knitting are in a state of crossing pinching" the threads for longitudinal knitting, it is aimed at mutually tightening up each adjoining bead without displacement and mutually stretching the finished knitted cushion which can further form a shaping with a curve to meet with the human body, so that when the user sits and leans thereon, he will feel its coincident performance and quite comfortableness. As shown in Fig. 6, the arcuate cushion (100) with elasticity can be installed on the seat (20) in the car for use. Since this cushion (100) is a separate and moveable cushion body, it fits in with various sitting and leaning gestures of human body including those who are tall, short, fat or lean. Even if anyone feels uncomfortable since he sits and leans thereon for a long time, he can adjust the position of said cushion (100) from time to time (such as changing it in an inclined position as shown in Fig. 7), so the cushion of the present invention is provided with a function of changing one's sitting and leaning positions as one likes from time to time, and all the users can feel its coincident performance and quite comfortableness regardless of their different physiques. In addition, since the cushion (100) is knitted with the beads (16), so it has a plurality of pores or gaps which is instrumental to the heat radiation of human body so the user will feel more cool, ventilative F and comfortable. As shown by another example in Figs. 8, 9, 10 and 10-1, various textiles (such as jean (denim), synthetic leather, non-woven clothe or network cloth) may be used as the materials to knit the cushion. As shown therein, a plurality of cloth holes (31) are correspondingly provided to the margin of the four sides of textile (30) in keeping with a plurality of longitudinal guide holes (11) of frame body (10). When to assemble the textile (30) with the frame body (10), barbed spikes (32) are inserted in the cloth hole (31) of textile (30) and the longitudinal guide hole (11) of frame body (10) so as to fix both textile (30) and frame body (10) in one to finish the preparation of the cushion of the present invention.
