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.

The present disclosure provides a tolerance compensation fastening assembly for fastening a first component to a second component which comprises a first compensation element and a second compensation element. The first compensation element comprises a first support portion which is provided with a first receiving hole that receives a shank of a fastener, and is connectable to the first component and movable relative to the first component in a longitudinal direction. The second compensation element comprises a second support portion which is provided with a second receiving hole that receives the shank of the fastener and is connectable to the first component and movable relative to the first component in at least one transverse direction perpendicular to the longitudinal direction. The first support portion and the second support portion are subjected to an axial fastening force applied by the fastener, and are at least partially made of metal.

The present invention provides a shower door adjusting device comprising a first side frame and a second side frame; a first fixing base assembly including a first fixing base and a second fixing base, wherein the first fixing base is fixed on the first side frame, the second fixing base is detachably fixed on the first fixing base, an installation groove is formed in the first and second fixing bases, and the first fixing base assembly is provided with a first through groove therein; a locking sheet whose end is provided with a boss, wherein the end of the locking sheet is installed in the installation groove, the locking sheet is provided with a first locking hole which faces the first through groove; a first connecting bar fixed to the second side frame and provided with a first rack passing through the first locking hole and the first through groove.

The invention concerns a fastener comprising a foot and a head comprising a plate to which said foot is linked, a wedge and a shank connecting said plate to said wedge, which comprises a back-plate, a rim and flexible arms connecting said rim to said back-plate, each arm comprises a first and a second curved section, and an elbow connecting them, said first section is connected to said back-plate by a first end of said arm and said second section is connected to said rim by a second end of said arm, said back-plate and each flexible arm are configured such that the distance between the center of said back-plate and said second section increases along said second section from said elbow to said rim.

A method and apparatus is provided for adjusting a latch. An apparatus comprises a latch body, a first member, and a second member associated with the latch body. A receiving area extends through at least a portion of the latch body. The first member is configured to be at least partially received within the receiving area of the latch body. The first member has a first coupling element. The second member has a second coupling element. Movement of the first member along an axis through the receiving area changes a distance between the first coupling element and the second coupling element.

A fixing device for fixing of two bodies to each other, for example a panel to a wall or two panels to each other, includes a male element having a support base and an engaging element, the support base having a rear surface for leaning onto one of the two bodies to be connected and a front surface from which the engaging element protrudes; and a female element having a support base with a rear surface for leaning and fixing onto the other body and a receiving channel for receiving the engaging element of the male element so that the engaging element, when inserted into the receiving channel, snaps inside it detachably, thus enabling the releasable coupling of the two bodies. The fixing device is configured for selecting two or more different distances along the axis defined by the rear surfaces of the male and female elements when coupled.

A fastener assembly may include a pin including a central shaft connected to a distal tip, and a grommet including at least one leg. The pin and the grommet are configured to be positioned in an expanded state in which the fastener assembly securely fastens to the component, and a retracted state in which the leg(s) is drawn toward the central shaft to reduce an axial envelope of the leg(s).

A fastener is adapted for assembling a first housing to a second housing. The first housing is provided with a protruding portion and a buckling portion, and the second housing has a first surface, a second surface, and a through hole. The fastener includes a first portion, at least one connecting portion, at least two elastic portions, and a second portion. The first portion movably abuts against the first surface and has a first opening. The connecting portion is accommodated in the through hole. One end of the connecting portion is connected to the first portion. The connecting portion is spaced apart from an inner edge of the second housing by a gap. The two elastic portions inclinedly extend into the first opening. The second portion movably abuts against the second surface and is disposed at the another end of the connecting portion.

A display device is disclosed. The display device may include a display panel and cover. A first cover may be configured to be connected to the display panel and a second cover may be connected to the first cover to cover the display panel. The first cover and the second cover may cover a back side of the display panel. A plurality of first holders may be disposed on the first cover and a plurality of second holders may be disposed on the second cover corresponding to the plurality of first holders to couple the second cover to the first cover. The first cover may include a first frame and a second frame connected to each other. Distal ends of the first and second frames may have prescribed shapes configured to couple to each other to form a low profile cover for the display device.

A device for compensating for tolerances between two components to be connected by means of a connecting screw, comprising a base element, a compensating element which can be moved out of the base element, the base element and the compensating element forming a passage for the connecting screw, which passage defines an axial direction, and a retaining element for retaining the base element.
