Plastic adjustable accelerator pedal with internal drive mechanism
First Claim
1. An adjustable control pedal comprising, in combination:
- a mounting bracket;
an upper support forming a hollow interior space;
wherein the upper support is pivotably mounted to the mounting bracket;
a pedal arm having a lower end carrying a pedal;
wherein said pedal arm has an upper end extending into said interior space and supported by said upper support within said interior space for selected movement relative to said upper support;
wherein said interior space is enclosed by said upper support except for an opening at a bottom side of the upper support for passage of the pedal arm;
a drive assembly operatively connected to the pedal arm to selectively move the pedal arm relative to the upper support;
wherein said drive assembly includes a drive screw supported for rotational motion within the interior space of the upper support and a drive nut adapted for axial movement along the drive nut in response to rotational motion of the drive screw; and
said drive nut is operatively connected to said pedal arm to axially move said pedal arm along said drive screw with said drive nut.

Abstract
An adjustable control pedal includes a molded-plastic upper support forming a hollow interior space. The upper support has a pair opposed side walls partially forming the interior space and opposed flanges inwardly extending into the interior space from the side walls. The opposed flanges are molded-in flanges unitary with the upper support. A pedal arm has a lower end carrying a pedal and an upper end provided with at least one guide pin slidingly supported by the opposed flanges for selected movement of the pedal arm relative to said upper support. The interior space is entirely enclosed by the upper support except for an opening at a bottom side of the upper support and the upper end of the pedal arm extends into the interior space through the opening. A drive assembly is operatively connected to the pedal arm to selectively move the lower arm relative to the upper support. The drive assembly includes a drive screw supported for rotational motion within the interior space of the upper support, a gear mechanism located within the interior space and operatively connected to the drive screw for rotating the drive screw, and a drive nut adapted for axial movement along the drive screw within the interior space in response to rotational motion of the drive screw. The upper support includes unitary molded-in journals supporting components of gear mechanism. The drive nut is operatively connected to the pedal arm to axially move the pedal arm along the drive screw with the drive nut as the drive screw rotates.
