丄 V 丄 厶 呻 岭 〇 厶 丄 V. Creation Instructions (1) [Technical Field to which the New Type belongs]

This creation is about a seat adjustment, a type of seat backrest, a lift-type cushion body structure, and a waist structure, in particular, it refers to the connection, so that the carcass can be folded back between the chair and the back of the chair. The sections are folded back together to form a ^ Kai swing 'or make the carcass towards the cushion structure to achieve the pivotal connection;; :: Jin "J, which in turn promotes the function of the back of the chair and facilitates the adjustment of the U lift in sections. Opening bracket and folding backrest [pre-different technology] '' Traditional seat back waist cushion structure, the post pile 4 β ^ leaning on the front of the chair back, Akayama & North System will be directly attached The waist ^ ^ ^ ± or by the internal connection of the transmission assembly of the chair, and the internal backboard of the driving seat is used as the lower part of the seat. The seat back side upright is # # ^ & In the actual assembly and operation, it has the following treasures: a large attached waist-cushion system plus Xiao's use of the seat's overall shape 2; it does take up a lot of time The shelving space. The telescoping distance from the chair is over the internal telescoping displacement of the lumbar support, which is often limited by the driving support. The effect of support and the transmission of the waist are like the other backrest which is placed on the backrest of the telescopic displacement inside the seat back. F cooperates with the extra disk 4a # to drive the inner backboard of the seat back to perform the telescopic displacement to form the burden of parts and assembly costs. Μ 疋 ^, How to develop a waist cushion structure different from the traditional seat back? The waistrest is combined with the seat back and has a highly interoperable extended structure, Θ5Θ4 Page 4 M244821

V. Creation Description (2) Long: for the combined effect of the launch of the crime and the crime of folding off, and the convenience of segmented adjustments. 'The new products that consumers really want are also required by related industries.' aims. % [New content] a. Technical problems to be solved This creation is aimed at the waist cushion structure of the seat back, which is directly integrated with the seat back to provide a highly interoperable lift bracket. Designed for the purpose of segmented adjustment and collapse operation. b. Technical means to solve the problem ° The main benefits of this creation are the floor panel and chair back lifter, which in turn provides a base lift structure, which can be folded for the main purpose of the chair back panel between different processes, or In order to promote the chair support and other main devices, you can provide a '' 'ι non, dry feather |: for the waist, a cushion body is provided on the other side of the waist section, and the cushion body is lifted by The folding device is connected, so that the cushion body can be folded relative to the seat back, and can be folded toward the waist portion of the seat back. The back cushion structure with its characteristic back can achieve the pivot connection setting. The main purpose is to provide a seat adjustment type using a pivot seat, a pivot lever, and a positioning ratchet to adjust the positioning angle of the lifting support of the positioning pad body to support the lifting effect, and to facilitate segmentation. The effect of adjustment The original waist-back structure completed in accordance with the above purpose, the main π seat adjustment and adjustment methods are to attach a cushion to the waist section on the front side of the seat back, and the inner surface of the carcass. I ^ ascended the body, lifted up the back of the chair, plus Tian Gubo Catching rabbits lost contact, the pad body can press seven 'or to the mat body have foldable seat back waist section

It is a six-point payment system that consists of one, one, and one stupid waist. The flip opening, the pivot seat, the yoke bar, and the positioning ratchet are connected between the inner panel of the cushion and the seat back panel, so that the lift & adjust: Support angle to provide no = support effect. Crazy waist c. Contrast the effectiveness of the previous technology. 1. Promote the structure of the waist cushion of the seat back to reach the pivot frame. # Eliminate the obstacles to the overall shape of the seat, and provide the interaction between the backrest and the seat back. &Quot; Use The effect is to completely solve the leftover space occupied by the waist cushion when the body is removed. 2. The cushion body can be directly moved to the lower part of the seat back to form a waist cushion. It reaches the ice V / pivot supported by the backrest, and is connected to the backrest body provided on the back of the chair, which does not need to match the amount of telescopic displacement. It also eliminates the negative protection of parts and assembly costs. : Yes-^ ϊ + ΐ ί ί ί members can elaborate on the characteristics, features, and effects of this creation, such as ^: 'Please cooperate with [Schematic Description] For details, please refer to Figures 1, 2, and 5-^ Waistrest structure, which is mainly provided by the system-a seat adjustment by the folding device ⑶) J = plate (= with the seat back (1〇) plate ⑴) * As shown in Figure 4, 5 The body (2〇) can be M244821 V.
