DETAILED DESCRIPTION
[00014] Typically, in two-wheeled motor vehicles the rear portion of the frame structure comprises a pair of tubes extending in a longitudinal direction. The rear tubes are generally made of a rigid material like metal. Plurality of brackets is provided on the rear portion of the frame structure to mount the seat assembly. Also, the two-wheeled vehicle or vehicles with similar layout includes rear side covers that cover both the frame portion from outward in a vehicle width direction in order to improve appearance of the vehicle. The rear side covers project outward and also rearward. Also, the rear covers house a tail lamp assembly of the vehicle. Thus, the rear portion of the frame supports the various aforementioned and other parts of the vehicle. In addition, plurality of ancillary components like latch assembly, tool kit, or battery is mounted to the frame structure.
[00015] Typically, mounting of the seat assembly requires a rigid support member that is welded to the rear tubes. Similarly, the vehicle includes various aforementioned parts that are mounted to the rear portion of the frame. This requires provisions of additional support members that are welded to the rear tubes. Provision of plurality of support members that are welded to the rear tubes requires multiple welding to be done on the rear tubes. The rear tubes being provided with relatively smaller cross-sectional compared to the other portions of the frame is subject to deformation due to the welding of multiple support members, which alters the alignment and also structural strength. Also, provision of multiple support members is time consuming during manufacturing and assembly.
[00016] Moreover, welding of the multiple brackets creates variation with respect to the mounting of the components being disposed adjoiningly. For example, the rear side covers that are essential parts of the vehicle that provide aesthetic appearance and in some high-speed vehicles provide aerodynamic function, requires precise assembly. As any interference between the components due to the variations affects proper fit. In addition to the interference between the components, the seat assembly (which is a load receiving member) mounted above the rear side covers may damage the rear side covers due to interference occurring between the components, especially when the rider sits. Such damage due to the interference with the rear side covers or may further creates create gaps resulting in entry of water or dust due to gaps therebetween, which is not desirable. For example, the rear cover assembly may accommodate essential parts of the vehicle like the electronic control unit, wiring harness, or air filter. These parts become vulnerable to entry of water or dust affecting their function. Thus, it is desirable to reduce interference during mounting itself. Also, the tail lamp assembly being housed in the rear cover assembly also requires minimum interference between them to avoid failure of the parts due to interference or due to gaps, which also affect the aesthetics of the vehicle.
[00017] Thus, there is a need for a sub-frame member for a motor vehicle that addresses the aforementioned and other problems in the prior art. The sub-frame member should be capable of supporting the various components mounted thereon of the vehicle like a seat assembly, rear side covers, and tail lamp with proper fit. Also, the manufacturing time and assembly time for the sub-frame should be reduced.
[00018] Hence, the present subject matter provides a sub-frame member for a vehicle disposed at a rear portion of the vehicle and mounted to a main frame member. The sub-frame member of the vehicle is provided with an integrated bracket that supports at least a portion of the seat assembly, a rear side cover assembly, and capable of supporting the tail lamp housing of the vehicle.
[00019] The sub-frame member includes plurality of rear tube members.

An integrated bracket disposed at a rear portion of the sub-frame. In one implementation, the integrated bracket supports the pillion seat. Also, the integrated bracket supports the rear cover assembly, a latch assembly, and tail lamp housing.
[00020] The sub-frame member supports a rider seat bracket that is disposed at a front portion thereof and the rider seat bracket is detachably mounted. Thus, the rider bracket can be removed to access the components disposed below with ease.
[00021] Further, the integrated bracket is connecting the at least a pair of rear tubes and is being disposed at a rear end portion of the of the sub-frame member. Further, in one embodiment, the integrated bracket includes at least a portion extending beyond a rear end portion of the sub-frame member. Also, the integrated bracket includes at least half portion, along the length, disposed between the pair of the rear tubes. In another implementation, substantially two-thirds, along length of the bracket, is disposed between the first pair of rear tubes and remaining substantially one-third of the length of the integrated bracket extends beyond the rear end portion thereof. Thus, the integrated bracket being supported by the rear tubes of the sub-frame is capable of withstanding the load(s) acting thereon. It is an advantage of the present subject matter that the integrated bracket provides improved rigidity for supporting vehicle components.
[00022] Preferably, the integrated bracket includes a length, taken along longitudinal axis of the vehicle, to be substantially greater that a width, taken orthogonal to the longitudinal axis of the vehicle. Thus, the integrated bracket extends along at least a portion of the sub-frame, whereby the integrated bracket is capable of supporting plurality of components.
[00023] In one implementation, the integrated bracket is made of a sheet metal, which is rigid yet has less weight and occupies less space.
[00024] The rear cover assembly including a right side cover and a left side cover converge towards the rear portion, wherein a rear end portion of the integrated bracket is adapted to support the rear end portion of the rear cover assembly without interference. Thus, in such implementation, the integrated bracket has a width receding from the front portion towards the rear portion to match the profile of the rear cover assembly and also profile of the rear tubes supporting thereof.
[00025] In one embodiment, the integrated bracket includes an access portion, which is preferably an aperture. The access portion of the integrated bracket provides access to components disposed below the integrated bracket, in an assembled condition of the integrated bracket on the vehicle. For example, a tool kit or the like is accessible through the access portion of the integrated bracket.
[00026] Further, the integrated bracket includes a front portion comprising a lock mounting portion used for mounting a lock assembly that enables locking the pillion seat. Further, the integrated bracket includes a rear portion that includes a cover mounting portion for mounting the rear cover assembly and a seat mounting portion for mounting the pillion seat.
[00027] Furthermore, the integrated bracket includes flanges provided about at least a portion of the integrated bracket. In one implementation, an inner flange portion extending along at least a portion of the inner edge portion of the integrated bracket is provided. Similarly, an outer flange portion disposed along at least a portion of the outer edge portion of the integrated bracket is provided. The flange portion(s) are preferably integrally formed. The flanges provide structural strength for supporting the plurality of components being mounted to the integrated bracket.
[00028] In one another embodiment, the integrated bracket is provided with protruded portion extending along at least a portion of the integrated bracket. The protruded portion provides improved surface area for supporting the loads thereby improving structural rigidity and strength of the integrated bracket.
[00029] In one embodiment, the integrated bracket includes a selected portion used for welding or affixing to the pair of rear tubes. Preferably, the length of the selected portion is less than the length of the integrated bracket portion facing the rear tubes. It is an advantage that the number of welding or the welding length required for securing the integrated bracket to the rear tubes is reduced. Thus, it is another advantage that the reduced welding reduces the deviation of the sub-frame member. Besides, the integrated bracket enables proper assembly of the rear cover assembly and the pillion seat with minimum interference and gaps therebetween.
[00030] Further, the integrated bracket helps in reducing number of components required to mount the vehicle parts. Furthermore, the integrated bracket includes a stamped portion forming a dent to support mounting portion(s) provided on a bottom portion of the pillion seat.
[00031] Further, the integrated bracket is capable of supporting one or more brackets affixed thereto without welding. For example, a secondary bracket affixed to the integrated bracket through fasteners is used for mounting the rear cover assembly. Thus, additional welding is eliminated.
[00032] Also, the integrated bracket provides common mounting provisions for mounting the rear cover assembly and the secondary bracket. Further, the secondary bracket supports the tail lamp housing. It is an advantage that the secondary bracket improves the reach of the integrated bracket for supporting the parts like tail lamp housing disposed at the rear end portion of the rear cover assembly.
