At a vehicle seat 10, a cushion material 18 is provided at a frame 14 for a sitting portion of a seat frame 12, such that a seat cushion 20 is formed. An upper cushion member (three-dimensional solid knit fabric) 86, which is a surface layer portion of the cushion material 18, is stretched at the frame 14 for the sitting portion, and is layered on a cloth spring material 18 which is a lower layer portion of the cushion material 18. When the cloth spring material 68 is pressed and flexes downward due to pushing-against force which is based on body weight of a seated person at a time of sitting on the seat cushion 20, at regions of the cloth spring material 68 which are pushed by ischial tuberosities of the seated person, tensile forces of extension coil springs 80, which are forces in the pushing direction, act, and directions of tension of the cushion material 18 are in three dimensions.

There is provided a vehicle seat including a seat frame which supports a load of a sitting passenger, a seat pad which is set on the seat frame and receives the load of the sitting passenger to be relieved, and a support body which is supported to the seat frame and supports a part of the seat pad from a backside thereof. The support body is supported to the seat frame to be slidable in an in-plane direction of a plane supporting the load of the sitting passenger or to be axially rotatable in an out-of-plane direction of the plane, such that the load of the sitting passenger can be relieved. The seat pad includes a fixed part which is supported to the seat frame at a fixed position and a movable part which is supported to the support body to be movable.

A surgical clip includes a pair of opposed arms joined at one end by an integrally formed flexible hinge, which may contain multiple cut-out spaces or finger-like projections and may be severable. A male locking pin near the free end of one arm is configured to penetrate tissue when the male locking pin is urged towards a mating female aperture near the end of the opposite arm. The clamping side of an arm may include a protruding feature, such as a wedge shape elongated ridge, while the clamping side of the opposite arm includes a corresponding trough or aperture that receives the protruding feature. Clamping surfaces may include non-slip protrusions, such as ribs, ridges, cones or pins. Rectangular cross-section alignment guides are provided to maintain clip alignment in the applicator.

A body contoured tub has a reclining surface that is molded to receive a user's reclining or recumbent body. In a first embodiment, the tub's interior contours are defined in a body measurement process that determines the users body contours, and then a custom fabricated tub is made to support the user's reclining body in a manner that permits extended use of the tub without excessive pressure anywhere on the user's body. In a second embodiment, the tub's interior contours are defined using representative body contours for a selected group of intended users of the tub.

A system and a method are provided for controlling a rotating type seat of a self-driving vehicle. In particular, seat position and bolster volume are adjusted based on a pressure rate in response to a vehicle turning when seat of the self-driving vehicle is rotationally adjusted in a desired direction. Accordingly, body displacement due to a centrifugal force and inertia is supported and a stable seating feeling is provided to the passenger.

Apparatus and method of a valve assembly that may be integrated into an inflatable device. The valve assembly may include a valve that is rotatable within a housing. The valve may allow for one-way passage of air either into or out of the inflatable device depending on the configuration of the valve. The valve system may provide an easy way to both inflate and deflate an inflation device with minimal effort from a user.

The invention discloses a back cushion core of a seat and a manufacturing method of the back cushion core, aiming at solving the problem that existing commercial back cushions, since polyurethane forming cotton is relatively high in cost, are high in cost. According to the technical scheme, the back cushion core is characterized by comprising a polyurethane forming cotton skeleton, a mounting through slot which is arranged in the polyurethane forming cotton skeleton and a U-shaped semi-slot which is arranged around the mounting through slot and communicates with the mounting through slot, wherein a sponge inner core is embedded in the mounting through slot; a U-shaped pearl cotton outer core is embedded in the U-shaped semi-slot; the sponge inner core and the U-shaped pearl cotton outer core are bonded on the polyurethane forming cotton skeleton via adhesives; and the polyurethane forming cotton skeleton is greater than the sponge inner core and the U-shaped pearl cotton outer core inhardness. Under the circumstance of guaranteeing same comfort with back cushions which are integrally manufactured by polyurethane forming cotton, other materials can be used for replacing the polyurethane forming cotton, so that cost of the back cushion can be reduced.

The invention discloses a method for adjusting the sitting posture and the softness and hardness of the seat, which is carried out according to the following steps: firstly, a backrest chair is designed, the backrest chair includes a seat board and a backrest located at the inner edge of the seat board, the backrest and the seat board The joints are hingedly connected, and the back of the backrest is provided with a chute closed at both ends along its height direction; then, the pressure sensor starts to collect pressure values ​​when the person just sits on the seat board, and the duration of the collection is not more than 1S , the pressure sensor transmits the pressure value of this time period to the controller for calculation and analysis to obtain the average value B; finally, the controller extracts the average value A to subtract the average value B, when the difference between them is divided by the average When the percentage obtained from the value A reaches the set value X, the telescopic device drives the backrest to rotate and push toward the back side of the sitting person. The method for adjusting the sitting posture and the soft and hard comfort of the seat can automatically correct the sitting posture and prevent the seat from sliding and being damaged.

The invention discloses an intelligent adjustment method for sitting posture, which is carried out according to the following steps: (1) Hinge the backrest of the chair and the seat cushion of the chair, install it for supporting the backrest so that the backrest can rotate relative to the rear side edge of the seat plate to (2) a pressure sensor for sensing the pressure of a person sitting on the seat board is set under the seat cushion of the seat; (3) the pressure sensor begins when the person just sits on the seat board The pressure value is collected, and the duration of the collection is not more than 1S. The pressure sensor transmits the pressure value of this time period to the controller for calculation and analysis to obtain the average value B; (4) the controller extracts the average value A to subtract the average value value B, when the percentage obtained by dividing the difference between them by the average value A reaches the set value X, the retractable device drives the backrest to rotate and advance toward the back side of the sitting person. The intelligent adjustment method of the sitting posture can automatically correct the sitting posture and prevent the seat from sliding and being damaged.

The invention discloses a seat cushion extension device, comprising: a sliding track, which is arranged on the lower side of the cushion frame; an extension plate, which is connected to the front end of the sliding track and is arranged on the front side of the seat cushion frame; an extension motor , which has a lead screw, and the extension motor is arranged on the underside of the cushion frame; a first hinge bracket, which is coupled to the end of the sliding track and arranged on the rear upper side of the extension plate; and a second a hinge bracket, which is coupled to the end of the lead screw and disposed on the rear lower side of the elongated board; wherein the elongated board is configured to slide forward along the sliding track, and is passed by the Actuation of the extension motor driven lead screw extends forward while turning the upper front.
