An undercarriage structure of a motor vehicle has a pair of front frames, a pair of floor frames integrally connected with rear ends of the front frames, a floor panel attached to the floor frames, and side sills extending in a front/rear direction and being connected with the sides of the floor frames. The floor frames, the side sills and the floor panel together form closed sections extending in the front/rear direction.

Undercarriage structure of motor vehicle

A reinforced floor structure for an automotive vehicle includes a tunnel member protruding upwardly and extending in a direction to the front and rear of the vehicle, a pair of front floor panels disposed at right and left sides of the tunnel member, a rear floor panel connected with the front floor panel via a stepped portion having a vertical wall, with the tunnel member extending backward so as to penetrate the vertical wall and being connected to a lower surface of the rear floor panel.

Reinforced floor structure for an automotive vehicle

In a front vehicle body structure in which a cowl front panel, which comprises an arcuated glass support portion for supporting a front window glass so that the glass support portion is located behind a dash lower panel at two side portions in the widthwise direction of a vehicle, and is located in front of the dash lower panel at a central portion in the widthwise direction of the vehicle, extends along the widthwise direction of the vehicle in a front portion of the vehicle, the cowl front panel is split into three members including two side split members and one central split member at positions where the glass support portion intersects the dash lower panel, and the two side split portions and one central split member are joined at the intersections.

Front vehicle body structure

A front body construction of a vehicle includes a lengthwise front side frame welded to the lower periphery of each of left and right wheel houses in the form of a substantially quatered spherical segment. Inner and outer extension frames different in length extend from the front side frame and are laterally spaced apart from each other. To the outer extension frame an apron frame welded to an outer edge of the wheel house is welded at its lower end. A frontal impact force is received by the inner and outer extension frames, specifically by the longer one at first and, then, by the shorter one when a buckling or crushing is caused in the longer one due to frontal impact force.

Front body construction

An arrangement for forming a rear partial structure of a vehicle body construction comprises, a rear end portion of a vehicle body forming an opening therein, a rear lamp assembly mounted on the rear end portion of the vehicle body so as to be disposed at a lower margin of the opening, and a tailgate mounted on the rear end portion of the vehicle body to be operative to open and close the opening. The tailgate includes a gate frame member which is attached through a hinge to the rear end portion of the vehicle body and a tailgate glass which is attached to the gate frame member and provided with an extended portion incorporated therewith to extend outward beyond at least a portion of one side of the gate frame member so as to cover therewith an outer surface of the rear lamp assembly when the tailgate is in a position for closing the opening.

Arrangements for forming rear partial structures of vehicle body

An automobile front body structure having an engine compartment defined therein, and also having a pair of spaced first longitudinal frames extending beneath the engine compartment in a direction longitudinally of an automobile and connected at a rear end to a floor panel. The front body structure comprises suspension arm support members secured to front ends of the first longitudinal frames, respectively, for the support of left-hand and right-hand suspension arms, and a transverse connecting member extending between the first longitudinal frames in a direction widthwise of the automobile and having its opposite ends connected to the respective support members.

Automobile front body construction

A motor vehicle front body structure including a dash panel separating the engine compartment from the passenger compartment. The dash panel has an upper portion which is inclined forward at an transversely intermediate portion and rearward at the transversely opposite end portions so that the upper edge portion of the dash panel has a forwardly convex configuration to conform with a corresponding configuration of the lower edge of the windshield glass.

An arrangement for forming partially a vehicle body of the open-top type comprises a front header member provided at an upper end portion of a front windshield for interconnecting therethrough right and left front pillars which are provided at right and left side portions of the front windshield, respectively, and a center frame member including a lateral part which is connected at a front end portion thereof to a central portion of the front header member and elongates in the direction of the length of the body and a vertical part which elongates in the direction of the height of the body with its upper end portion connected to a rear end portion of the lateral part and its lower end portion connected to a floor panel member.

Arrangement for forming vehicle bodies

A vehicle body front structure including a wheel apron extending forward from a hinge pillar and having a front end connected with the radiator shroud. A wheel apron reinforcement structure comprises an inner panel member and an outer panel member. The inner panel member extends between the hinge pillar and the radiator shroud and connected to the wheel apron. The outer panel member is connected to the inner member to form a structure of closed cross-section which extends from the hinge pillar to a position rearward the radiator shroud. The structure of closed cross-section has a height which increases toward rearward. The hinge pillar is of a closed cross-section and provided with reinforcement ribs which bridge the space in the hinge pillar at a heightwise position where the wheel apron reinforcement is connected to the hinge pillar.

Front body structure for motor vehicle

An automobile body side structure including a front side outer panel and a rear side outer panel. The front side outer panel defines a side door opening and formed with a rear pillar reinforcement at the rear end of the side door opening. The rear side outer panel includes a rear fender outer panel section and a rear pillar outer panel section formed at the front edge portion of the rear fender outer panel section.
