Abstract
A lateral protection for motor vehicles in which at least one reinforcement extending essentially in the vehicle longitudinal direction is arranged on the inside of each door, whereby in case of an external force influence or action which occurs in the vehicle longitudinal direction the reinforcements, preferably constructed as hollow bearers, are supported in the vehicle longitudinal direction with one end each either directly or indirectly at a fixed structural part such as, for example, at an upright column or at a wheel casing or at a further reinforcement belonging to an adjacent door.
Claims14
In a protection device for a vehicle of the type including side doors, relatively fixed structural parts of said vehicle for defining the side door openings, and reinforcement means for absorbing lateral impact forces on said vehicle, said reinforcement means extending in the longitudinal direction of said vehicle inside said doors, the improvement comprising structural force transmission means at each end of said reinforcement means for directly transmitting longitudinal impact forces on said vehicle between said reinforcement means and relatively fixed structural parts such that said longitudinal impact forces on said vehicle are directed uninterruptingly in said longitudinal direction by said structural force transmission means and said reinforcement means, and
- wherein said structural force transmission means includes at least one of a profiled hollow structural member arranged between one end of said reinforcement means and said relatively fixed structural parts of said vehicle and a structural bar interposed between aligned facing ends of two longitudinally disposed reinforcement means of two respective longitudinally disposed side doors arranged at least at one side of said vehicle.
In a protection device for a vehicle of the type including side doors, relatively fixed structural parts of said vehicle for defining the side door openings, and reinforcement means for absorbing lateral impact forces on said vehicle, said reinforcement means extending in the longitudinal direction of said vehicle inside said doors, the improvement comprising structural force transmission means at each end of said reinforcement means for directly transmitting longitudinal impact forces on said vehicle between said reinforcement means and relatively fixed structural parts such that said longitudinal impact forces on said vehicle are directed uninterruptingly in said longitudinal direction by said structural force transmission means and said reinforcement means,
- wherein said structural force transmission means includes at least one of a profiled hollow structural member arranged between one end of said reinforcement means and said relatively fixed structural parts of said vehicle and a structural bar interposed between aligned facing ends of two longitudinally disposed reinforcement means of two respective longitudinally disposed side doors arranged at least at one side of said vehicle,
- wherein said profiled hollow structural member is mounted between said one end of said reinforcement means and an upright column of said vehicle, said upright column defining at least one portion of said side door openings, and
- wherein a hollow reinforcing member is secured to said one end of said reinforcement means and to said profiled hollow structural member such that said reinforcement means and said profiled hollow structural member are connected for transmitting said longitudinal impact forces.
In a protection device for a vehicle of the type including side doors, relatively fixed structural parts of said vehicle for defining the side door openings, and reinforcement means for absorbing lateral impact forces on said vehicle, said reinforcement means extending in the longitudinal direction of said vehicle inside said doors, the improvement comprising structural force transmission means at each end of said reinforcement means for directly transmitting longitudinal impact forces on said vehicle between said reinforcement means and relatively fixed structural parts such that said longitudinal impact forces on said vehicle are directed uninterruptingly in said longitudinal direction by said structural force transmission means and said reinforcements means,
- wherein said structural force transmission means includes at least one of a profiled hollow structural member arranged between one end of said reinforcement means and said relatively fixed structural parts of said vehicle and a structural bar interposed between aligned facing ends of two longitudinally disposed reinforcement means of two respective longitudinally disposed side doors arranged at least at one side of said vehicle,
- wherein said structural bar is mounted at a vehicle center column such that only said structural bar is interposed between said aligned facing ends of said two reinforcement means, and
- wherein means for movably mounting said structural bar to said vehicle center column are provided, said means for movably mounting displacing said structural bar into said vehicle center column during opening of one of said two doors.
In a protection device for a vehicle of the type including side doors, relatively fixed structural parts of said vehicle for defining the side door openings, and reinforcement means for absorbing lateral impact forces on said vehicle, said reinforcement means extending in the longitudinal direction of said vehicle inside said doors, the improvement comprising structural force transmission means at each end of said reinforcement means for directly transmitting longitudinal impact forces on said vehicle between said reinforcement means and relatively fixed structural parts, said structural force transmission means being mounted separately of vehicle door mounting devices such that said longitudinal impact forces on said vehicle are directed uninterruptingly in said longitudinal direction by said structural force transmission means and said reinforcement means,
- wherein said structural force transmission means includes at least one profiled hollow structural member mounted between a first end of one of said reinforcement means longitudinally mounted in a first side door of said vehicle and said relatively fixed structural parts of said vehicle, and a structural bar interposed between a second end of said one reinforcement means and an end of a second longitudinally mounted reinforcement means disposed in a second side door of said vehicle longitudinally adjacent said first side door at least at one side of said vehicle, said profiled hollow structural member being connected to said one reinforcement means by a hollow reinforcing member, and
- said profiled hollow structural member being disposed adjacent said relatively fixed structural parts of said vehicle at a predetermined gap which is bridged by abutment of said profiled hollow structural member and said relatively fixed structural parts of said vehicle upon occurrence of said longitudinal impact forces,
- said second end of said one reinforcement means and said end of said second reinforcement means being disposed adjacent said interposed structural bar at respective predetermined gaps which are bridged by abutment of said second end of said one reinforcement means and said end of said second reinforcement means with said structural bar upon occurrence of said longitudinal impact forces.
