A trailer includes a housing including an internal frame and an external frame. The external frame is coupled to the internal frame. In certain embodiments, the internal frame is positioned between interior panels and exterior panels of the housing. In certain embodiments, the external frame is spaced from exterior panels.

In a method for connecting an attachment part to a structural part of a bodywork, a wall of the structural part is formed to at least partly encircle a region of the structural part. A form element is arranged to a main body of the attachment part. The attachment part is placed in the region of the structural part such that the form element touches the wall of the structural part, and the attachment part is pushed into the region, thereby causing the form element to move in relation to the main body of the attachment part until reaching an aperture in the wall of the structural part so that the form element moves into the aperture and is arranged therein to thereby position the attachment part in the region of the structural part.

The invention discloses several types of fastener, fastening systems, fastener assemblies and related areas.

In particular, the invention relates to a releasable fastening system (50) which has a pin (152) with a locking cavity (163). The pin is intended for insertion in an aperture (154). A locking means (158, 160) engages the locking cavity (163) of the pin (152) when the pin (152) is received in the aperture (154). The system (150) also includes unlocking means (162) which includes material adapted to contract when activated. When a material contracts, engagement means (158) included in the locking means (158, 160), disengage the locking cavity (154).

A vehicle has a frame including a front frame module defining at least in part a cockpit, and a rear frame module having a cargo bed support structure. The vehicle has a rear seat row or a cargo bed support structure extension disposed rearwardly of a front seat row. A wheelbase length measured between centers of front and rear wheels of the vehicle is approximately the same regardless of which of the rear seat row and the cargo bed support structure extension is disposed rearwardly of the front seat row. A longitudinal cargo pivot distance measured between the center of the front wheels and a cargo bed pivot axis is approximately the same regardless of which of the rear seat row and the cargo bed support structure extension is disposed rearwardly of the front seat row. A method of assembling a vehicle of a family of vehicles is also contemplated.

Methods for fastening or coupling dissimilar materials to each other may include providing a first component with a first through hole and a second component with a second through hole that is at least partly aligned with the first through hole. A mixture including a first material and a second material may be injected into the aligned through holes of the first component and the second component. The mixture of the first material and the second material may expand in the through holes, e.g., due to a chemical reaction, thereby connecting the first component and the second component together.

A front portion of a vehicle body includes front side frames, a subframe, and a vehicle compartment front structure body. The subframe has a subframe body, a front fastening portion fastened to the front side frame in a front region of the subframe body, and a rear fastening portion fastened and fixed to the vehicle compartment front structure body in a rear region of the subframe body. The rear fastening portion has a first convex portion protruding toward a vehicle rear side. A part of a steering gear box constitutes a second convex portion protruding upward from the subframe body. The front fastening portion has a third convex portion protruding upward from the front region of the subframe body. The vehicle compartment front structure body has a first inclined guide portion, a second inclined guide portion, and a third inclined guide portion having front surfaces to contact the convex portions.
