The tire-mounted step stool is a step is adapted for use with a tire of a vehicle. When the tire-mounted step stool is secured to the tire, the tire-mounted step stool forms a platform upon which a person can step to gain access to the roof or engine compartment of the vehicle. The tire-mounted step stool comprises a first panel, a second panel, a first steel bar, a second steel bar, and a plurality of hinges. The first steel bar and the second steel bar are used to attach the first panel to the second panel. The plurality of hinges is used to make the stated attachments in such a manner that the tire-mounted step stool is collapsible.

A cargo box for a vehicle includes a base member having a first edge portion, a second edge portion, a first side edge portion and an opposing second side edge portion. A first cross sill extends across the base member. A second cross sill extends across the base member. A side panel member is coupled to the base member along one of the first and second side edge portions. The side panel member includes an opening. A step assembly includes a first step support coupled to the first cross sill, a second step support coupled to the second cross sill and at least one step member coupled to and extending between the first step support and second step support. The step member is arranged at the opening in the side panel member. The step member is decoupled from the side panel member.

A frozen accumulation detection assembly and method of operation for a motor vehicle is provided. The assembly includes a light source for emitting light on a surface of the motor vehicle, such as running board, and a sensor for measuring a reflectance level of the light off of the surface of the motor vehicle. The assembly further includes a heating element coupled to the surface of the motor vehicle. The reflectance level may be used as an indicator of frozen accumulation on the surface of the motor vehicle, and may help determine if the heating element should be energized.

The invention exhibits an apparatus for improving the aerodynamics of a commercial vehicle having a cab with doors and below-situated footboards for climbing in and out, and having a front panel in which air inlets are present, wherein the air inlets are connected, via air ducts in or on the panel, to the front wheel case of the commercial vehicle and to an air outlet, wherein the at least one footboard of the cab can be folded away and has at least one through-flow region in the vehicle longitudinal direction.

A pet ramp system has a central pier and at least one ramp with an axle that is received in an axle receiver disposed near the top of the pier. The axle is disposed inwardly, in both a fore and aft direction and in a transverse direction, from a base perimeter of the pier. The pier's axle receiver(s) permit installation of the ramp axle when the ramp is in a vertical orientation, but the receiver(s) will not permit separation of the ramp from the pier when in use.

The present invention relates to a hitch step that may be secured to a vehicle in a hitch receiver, and a method of manufacturing the same, that overcomes the disadvantages of the prior art. The present invention provides a multi-step pressurization method that produces a strong, compact hitch step that is cost effect to manufacture.

A portable ladder having a pair of elongate stiles spaced from one another and each having first and second ends, and extending in a first direction; and a plurality of rungs each extending between the elongate stiles transverse to the first direction and having opposed ends one of each attached to each of the elongate stiles and each of the plurality of rungs being spaced from one another along the first direction, the rungs being arcuate in shape between the opposed ends.

A hitch-mountable, collapsible stair assembly is disclosed for use in assisting mounting into a raised vehicle bed. The steps rotate between a generally vertical stowed position and a generally horizontal in-use position. The height of the steps above the ground is adjustable. The lower step can also be extended for ease of use.

A modular side rail and removable step system for a vehicle is disclosed. In one aspect, the kit includes first, second, and third removable steps that may be mounted to the side rail. In one aspect, the side rail main body has a channel-shape defining a longitudinal opening between an adjacent first side and an adjacent second side. A plurality of step attachment arrangements may be provided on the first side of the side rail main body to allow the first, second, and third steps to be mounted to the side rail main body in various configurations. For example the plurality of step attachment arrangements may be arranged and configured to provide attachment locations for mounting the first and third removable steps in a first step assembly configuration and for mounting the second removable step in a second step assembly configuration.

A detachable footrest assembly is provided. The assembly includes a frame having a first portion and a second portion. A footrest extends from the first portion of the frame. A first mount positioned such that the first mount is adapted to be received into a lower door hinge of a vehicle with a first pin that extends from a first mating portion which is threaded and which extends in a direction away from the first portion of the frame. A second mount is spaced apart from the first mount and positioned such that the second mount is adapted to be received into an upper door hinge of a vehicle with a second pin that extends from a second mating portion which is threaded and which extends in a direction away from the first portion of the frame. The first and second pins are substantially aligned.
