Powered retractable vehicle step assist systems and methods are provided. The steps systems are configured for installation (e.g., after market installation) and use with a vehicle. The system can include a stepping member movable between a retracted position and a deployed position with respect to the vehicle. The system can further include a vehicle interface configured to electronically communicate with an existing communication bus of the vehicle, such as through a connection with an existing electronics port of the vehicle. A controller of the step system can be configured to process information received from the vehicle interface and, based at least partly on the processing of the information, cause movement of the stepping member between the retracted position and the deployed position.

An extendable steering column includes a first jacket, a second jacket, an energy absorption strap, an indexing feature and a spring. The first jacket extends along an axis and the second jacket is disposed radially inward from the first jacket with the first and second jackets being in telescopic relationship to one-another. The locking shoe is in radial contact with the second jacket. The strap is fixed to the second jacket and disposed radially between the first and second jackets. The indexing feature facilitates a locked state and an unlocked state, and is carried between and defined by the strap and the locking shoe for telescopic adjustment of the steering column. The spring is disposed radially between the shoe and strap, and is constructed and arranged to bias the locking shoe radially away from the strap and toward the unlocked state.

A collapsible skateboard includes an upright handle having lower portion on which is fixedly mounted a bracket, a connector having a curved slot having a lower end formed with a horizontal recess, an upper end formed with a vertical recess, and a circular hole under the vertical recess, an adjust pin inserted into the vertical recess of the connector and the elongated hole of the bracket, a pivot pin fitted through the circular hole of the connector and the circular hole of the bracket, a spring having an upper end connected to the adjust pin and a lower end to the pivot pin, and a platform on which is fixedly mounted the connector, whereby the skateboard can be easily folded up as desired.

A vehicle door for a motor vehicle, including a support structure, an inner shell fixed to the support structure, and an outer panelling fixed to the inner shell. The inner shell is formed and connected to the support structure in such a way that it is a load-bearing component, thereby increasing the overall rigidity of the vehicle door.

Disclosed is a dog-bone type rear roll rod in which a body bracket, which is fixed to a vehicle body, and front and rear rubbers, which are disposed at front and rear sides of the body bracket, respectively, are connected together through an inner pipe and fastened to a rod by means of a fastening member, the dog-bone type rear roll rod including: an extrusion plate which has a through hole formed such that the inner pipe penetrates a center of the extrusion plate, has a width length greater than a width length of the rod, and is press-fitted between the rod and the front rubber.

A vehicle body side reinforcement assembly includes a first side reinforcement panel; an inner center pillar coupled to the first side reinforcement panel and to a floor support forming a lower portion of a vehicle body; and a second side reinforcement panel coupled to the first side reinforcement panel, the inner center pillar, and the floor support to form a closed structure at a lower portion of the side of the vehicle. This structure improves vehicle body performance during a side collision by transferring the collision load to the floor support, resulting in improved safety performance. In addition, the assembly minimizes the number of necessary parts and allows for low-cost assembly methods, such as spot welding, thereby reducing production costs and increasing marketability.

A pre-buck apparatus for a vehicle body assembling system comprises a pre-buck section and a main buck section that are set along a transfer path of a floor assembly. The pre-buck apparatus is formed in the pre-buck section, and while the side assembly is disposed in each of opposite sides of the transfer path in the pre-buck section, the pre-buck apparatus controls a lower portion of the side assembly, and the lower portion of the side assembly is pre-assembled to the floor assembly using a first welding robot.

A bicycle frame structure having a rear frame and a front frame includes a rear frame of which a left stay and a right stay are bonded to each other, and an insert portion is formed at a bonded end portion, and a front frame where a head tube is formed at a front end portion thereof, an insertion hole into which the insert portion is inserted is formed at a rear end portion thereof, and the front frame is bonded to the rear frame along the circumference of the insertion hole.

A brake device may include: a master cylinder including a master piston moved in connection with a pedal, and a master cylinder body having the master piston movably inserted therein and containing fluid of which hydraulic pressure is varied when the master piston is moved; a pedal force generation part housed in the master cylinder body, and restricting a motion of the master piston while interfering with the master piston depending on the motion of the master piston; a braking actuator configured to generate hydraulic pressure; an actuator connection part connecting the braking actuator to a brake mounted on a wheel; and a master connection part connecting the master cylinder to the actuator connection part.

A floor securing apparatus comprises a riser slot formed in a floor riser transverse to a longitudinal axis of the floor riser, the floor riser configured to support a floor sheet and a key including a locking head and at least one anchor tab, wherein the key is slidable into the riser slot transverse to the longitudinal axis of the floor riser, wherein the key is configured to engage a portion of the floor sheet to prevent vertical movement of the floor sheet relative to the floor riser.
