This invention relates to disposable and recyclable protective coverings for the top portion of a seat, such as those found in cinemas, theaters, and airplanes. The Disposable and Recyclable Protective Seat Covering consists of a belt, which fits to most seats, and a strap that runs overtop the seat and fastens on the back of the belt. The belt contains a raised head guard for user protection and comfort, and a pocket for storing small valuables. Also, an optional drape hangs from the belt and covers the front of the seat.

A seat assembly for an internal cabin of a vehicle includes a seat cushion, and a backrest pivotally coupled to the seat cushion. The backrest is moveable between a first position and a second position. The first position is configured to allow a passenger to sit on the seat cushion. The second position is configured to allow one or more cargo items to be secured on a rear surface of the backrest.

The present invention is a portable, intelligent, ergonomically adjustable body-seat cushion controlled wirelessly via a smartphone or tablet app. Multiple air bladders embedded in the body-seat cushion inflate/deflate at the direction of the app to manipulate the physical position of the user's neck, back, posterior, legs, and feet in order to: (1) alleviate pressure on the back and sit-bones; (2) lengthen the user from a normal sitting position to a lengthened sitting position; and (3) increase blood flow to the user's extremities. Positioning algorithms in the app use the user's anthropometric data (body measurements) and seat measurements (including available space above and in front of the seat) to generate one or more air bladder fill instructions to lengthen the user. The app then wirelessly transmits the positioning instructions as well as optional motion, temperature, and vibration instructions to one or more wireless receivers in the seat cushion.

The vehicle seat back according to the invention includes a textile assembly (30) having at least one embrittled linear zone (32, 32A, 32B) able to tear during an impact of the head of a passenger located on the seat behind the seat back considered, so as to enable rocking of this passenger's head to be continued and, at the same time, to be slowed down. Application to aircraft seats.

A flexible lumbar support for an aircraft seat includes a frame and flexible seat pad connected thereto for supporting a seat user. At least first and second rods are spaced from each other and the frame, extend across and are secured to the seat pad, and define respectively at least first and second control lines about which the seat pad is rotatable. A third rod is spaced from the seat pad, extends across and is secured to the frame, and defines a third control line. At least a first actuator extends between and is attached to the first and third rods. A second actuator extends between and is attached to the second and third rods. The actuators are movable along the frame and pivotable about the third control line for allowing a change of respective positions of the control lines to generate multiple profiles of the flexible lumbar support.

A frameless transit seat is used for carrying passengers in a transit vehicle. The transit seat is comprised of at least two pedestals which connect the seating portion to the vehicle floor and which distribute the weight of the seat and its passenger(s). Under the passenger, at least two side supports are affixed on top of the pedestals, and one or more crossbars or stabilizers, without any rack frame structures connecting the pedestals. A variant of the transit seat has two seats and uses a mounting plate to connect the two inner side supports to a central pedestal. The components of the transit seat include hollow beams, bent sheet metal, and other components optimized to decrease mass while retaining maximum strength. Optionally, the seat may recline and be upholstered in a variety of covering options.

A multifunctional portable seat cover kit includes a multifunctional portable seat cover (MPSC) and a drawstring carry case. The MPSC includes a first and second section, a compartment, and a flap. The first section includes a top and bottom surface. The top surface of the first section contacts a user contact surface and the bottom surface secures the MPSC to a top area of a seat. The second section flexibly extends from the first section. The second section includes a top and bottom surface. The top surface of the second section contacts the user contact surface and the bottom surface of the second section contacts the seat. The compartment is positioned on the bottom surface of the second section and houses a pillow and pouches for storing primary objects. The flap extends from the second section and seals the compartment. The drawstring carry case stores the MPSC and secondary objects.

A headrest structure for a passenger seat, a headrest cushion and passenger seat. The headrest structure comprises an adjustable headrest frame for connection to a passenger seat; and a headrest cushion mounted to the adjustable headrest frame such that the headrest cushion is moveable relative to a seat back of the passenger seat by way of the adjustable headrest frame; wherein the headrest cushion comprises a support surface facing away from the headrest frame, the support surface comprising a concave upper part and a convex bottom part relative to the passenger seat.

A seat back assembly for a vehicle such as an automobile or an aircraft includes a foam support structure. The foam support structure panel is configured to provide a support structure against which the upper body and/or back of a user rests in use. The foam structure may include two or more regions having different foam density and/or firmness.

A method of upholstering a seat having a seating frame, and a corresponding attachment assembly, comprises providing a diaphragm generally having a weave of warp and weft yarns with an attachment member for installation of the diaphragm to the seat. The attachment member comprises an adapter strip and a coil member. The coil member is adapted to be intertwined with the weave of the diaphragm and thereafter inserted into and held by the channel in the seating frame. The adapter strip may be connected to the coil member to facilitate feeding the assembly through the channel in the seating frame. Alternately, the adapter strip can replace the channel in the seating frame and instead provide a mounting structure to which the diaphragm can be attached through the coil member's engagement with the adapter strip. A retainer sheet may also be used to maintain a desired tension of the diaphragm during installation.
