Described are torque bearing assemblies for passenger seats. A torque bearing attachment (122, 222, 322, 422) includes an elongated body having a forward edge configured to mate with an aft end (140) of a seat bottom pan (120), and first and second side edges having attachment elements (136) for connecting the assembly with a passenger seat frame (108). The first and second side edges can be positioned orthogonal to the forward edge and at opposite ends of the elongated body with respect to each other.

A seat attachment system for a mass transit vehicle including a rail, a fastener and a seat interface. The rail, which is adapted to be secured to a chassis of the mass transit vehicle, has a longitudinal T-slot adapted to receive the fastener. The rail has two non-parallel sets of corrugations on its external face. The seat interface, which is adapted to be mounted to a seat frame, is also provided with two non-parallel sets of corrugations whose angle matches that of the sets of corrugations on the rail. The sets of corrugations are adapted to cooperate and interlock in pairs so as to respectively locate the seat interface, and thereby a seat to which it is attached, vertically and horizontally upon the fastener being tightened.

A seat cover including an elongate body sheet for placement between a user and a seat is provided. A pair of arm protectors extend laterally from sides of an intermediate portion of the seat cover. The arm protectors provide a barrier between the user and armrests. An adhesive strip is integrally formed with a back surface of the seat cover and proximate an upper portion binds the cover to the seat. A pocket is integrally formed with a front lower surface of the seat cover for storing a sanitizer container.

The subject of the invention is a frame for seats in public transport vehicles, used in vehicles such as trams, school buses or other vehicles for transporting passengers on short distances, with low requirements for the comfort of travel. A frame for a seat in public transport vehicles in the form of shaped bent profile that creates a backrest and a seat pan, to which brackets for the seat pan and backrest pillows are attached, wherein the profile (1) in a section perpendicular to its longitudinal axis has an outline similar to an ellipse and its longer section axis is tilted upwards in an outside direction from the vertical plane, which forms the frame's perpendicular bisector, by angle α ranging from 10-30°, preferably 20°.

A bus seat for use in a bus comprises a frame and a seat back secured to a portion of the frame. The bus seat further comprises a seat cushion secured to another portion of the frame. The bus seat also comprises a removable two piece cover arranged over the seat back, wherein the cover pieces are secured to one another with a zipper. The zippered two piece seat back cover allows for easy installation, removal or replacement of any damaged or worn portions of the seat back trim cover.

Described are aircraft seat frame assemblies comprising a tube and a seat frame component mounting system. The seat frame component mounting system comprises a first tube mounting member and a second tube mounting member separable from the first tube mounting member. The tube is positionable between the first tube mounting member and the second tube mounting member. The seat frame component mounting system further comprises a fastener extending at least partially through the second tube mounting member, the tube, and the first tube mounting member to couple the second tube mounting member to the first tube mounting member. A clamping force is substantially evenly applied from the second tube mounting member and the first tube mounting member against an outer circumferential surface of the tube via the fastener.

A transportation seat support apparatus includes a frame configured to support a transportation seat. The frame includes an attachment portion configured to attach to a wall of a transportation vehicle, and at least one beam extending from the attachment portion at a first end and terminating at a second end. The transportation seat support apparatus further includes a pedestal configured to support the frame. The pedestal includes at least one leg portion configured to attach to a floor of the transportation vehicle, and at least one aperture configured to telescopically receive the second end of the at least one beam. The at least one beam is slidably movable within the at least one aperture.

A tour bus includes a vehicle body, a front door, a rear door, a plurality of wheels, a luggage compartment door and a movable placing portion. The front door, the rear door and the luggage compartment door are all disposed at one lateral side of the vehicle body, with the luggage compartment door between the front door and the rear door. The wheels connected individually to a bottom of the vehicle body are used for displacing the vehicle body. The movable placing portion is foldably disposed in a storage area of the vehicle body. The movable placing portion includes a placing platform and a supportive structure. The placing platform can protrude out of the storage area of the vehicle body. The supportive structure is pivotally connected with the placing platform, and the supportive structure supports the placing platform while the placing platform is moved out of the vehicle body.

A stowable seat system includes a seat base and a seat frame operationally engaged with the seat base. The seat base includes a vehicle engagement portion adapted for operational engagement with an associated vehicle, and a seat engagement portion movably engaged with the vehicle engagement portion at a first actuation region. The seat frame includes a bottom portion, and a back portion movably engaged with the bottom portion at a second actuation region.

A monitoring system for buses includes presence sensors and belt sensors connected to slaves connected to a connection cable to transport the signals from the slaves in such a way to form a field bus. The connection cable is connected to a master that receives the signals from the slaves. The master is connected to a human-machine interface (HMI) by a network cable.
