  • Publication number: 20250340115
    Abstract: Embodiments herein are directed to a pedal emulator assembly including a housing having a cavity defined by a pair of sidewalls, a first end wall and a second end wall. A lower arm having a spring retaining portion is formed therein. A pedal arm is pivotally coupled the pedal arm and includes a pedal pad. A lever arm including a spring receiving portion is positioned within the cavity of the housing and is pivotally coupled to the housing. A spring carrier including a compressible member extends between the spring receiving portion and the spring retaining portion. When a first predetermined load is applied to the pedal pad, the pedal arm drives the lever arm into the compressible member and the compressible member compresses into an at least partially compressed state to generate a first return force on the pedal pad.

  • Publication number: 20250291378
    Abstract: The present disclosure is directed to a pedal assembly that includes a pedal arm configured to move based on a load applied thereon and a housing that includes a first housing member having a first cavity and a pushrod operably connected to the pedal arm and to the first housing member. A first cradle positioned within the first cavity. The first cradle includes a second cavity. A first pair of springs positioned to extend within the second cavity. A second housing member having a third cavity. A second pair of springs positioned to extend within the second cavity and the third cavity. When a first predetermined load is applied to the pedal arm, the pushrod moves which drives the first cradle against the first pair of springs such that at least a compression energy by the first pair of springs generates a first force feedback onto the pedal arm.

  • Publication number: 20250269718
    Abstract: An enclosure formed around a volumetric space in three dimensions affixed shells via blind sliders is disclosed. The space may be formed from a plurality of panels around at least a portion of the volumetric structure. The method and system provide a releasable enclosure around the structure or a rack or the like formed by attaching a plurality of shell components which nest in a sequential pattern over the structure via the blind latching assemblies formed on the interior wall surface of shell components to blind catching assemblies attached to the structure and wherein the latch and catch assemblies releasably affix the enclosure shells to the structure and together without the use of threaded fasteners; and, wherein the shells components are nested and evenly disperse force along the perimeter edges where the shells overlap.

  • Patent number: 9796363
    Abstract: A pedal assembly mounted to a vehicle includes, a pedal arm having an upper portion and a lower portion and a striker bracket pivotally connected to the upper portion of the pedal arm where the striker bracket further removably connected to the lower portion of the pedal arm. A first positioned is defined before a collision where the striker bracket is connected to the lower portion of the pedal arm. A second positioned is defined after a collision where the striker bracket rotates away from the lower portion of the pedal arm.

  • Patent number: 9645600
    Abstract: A two piece pedal arm assembly which forms a shell forming an internal cavity is provided. The two shell piece pedal arm permits the ability to carefully control wall thicknesses. This permits the ability to provide the proper strength where needed in complex designs resulting in weight savings. Additionally, other components such as the bracket and cage for a ball and booster arm, pedal adjusters, and the like can be mounted within the shell thereby providing robust attachment and a more pleasing appearance.
