A protective shroud includes a shroud body, a protective door movably installed on the shroud body, and a buffer mechanism connected between the shroud body and the protective door. The buffer mechanism slows down a moving speed of the protective door. The protective door is moved between an open position and a closed position in a vertical direction to open or close the shroud body.

A linear actuator includes a jacket defining an axis and a rod having an end cylinder tightly slidable in the jacket and an opposite end sliding between a rest position and a working position. The end cylinder divides the jacket into a first and a second variable volume compartments fluidly independent from each other, one of them being fluidly insulated and under vacuum, the other one being fluidly communicating with the outside environment. Upon the passage of the opposite end of the rod from the rest position to the working position, one of the variable volume compartments passes from a minimum volume to a maximum volume, in order to suck the rod and automatically recall the opposite end from the working position to the rest position.

A drive for adjusting an adjustment element of a motor vehicle, the drive including a hollow cylinder, a rod guided axially therein, two articulated parts configured to provide linear drive movements to the motor vehicle and form a drive connection to the adjustment element and the rest of the motor vehicle. The one articulated part axially fixed to a first component of the components of the drive unit and the other articulated part axially fixed to a second component of the components of the drive unit in the installed state. The drive has a drive spring assembly including a drive spring acting on the articulated parts. In the installed state, at least one of the components of the drive unit is axially fixed to a securing element by a threaded connection, and the securing element projects radially into an axial projection of a spring material of the drive spring assembly.

A method of allowing access to a receptacle for securing a package includes: sensing an opening and closing of the lid; activating, in response to determining the lid is sufficiently closed, the lock mechanism to transition from the unlocked state to the locked state; scanning an email message in a user's email account to identify a reference or tracking number of a second package; parsing the email message to obtain a delivery code; receiving entry of the delivery code; activating the lock mechanism based on entry of the delivery code to transition from the locked state to the unlocked state; sensing a second opening and closing of the lid; activating the lock mechanism to transition from the unlocked state to the locked state; receiving information corresponding to entry of an access code; activating the lock mechanism to transition from the locked state to the unlocked state.

The disclosure relates to a drive arrangement for movement of a tailgate, wherein at least one drive unit is provided, having two drive connections, wherein a first drive unit is motor and spring-operated and has a drive unit motor as well as a drive unit spring, respectively acting on the two drive connections associated with the first drive unit, wherein the first drive unit comprises a movement sensor, representing movement information regarding a movement between the drive connections, wherein a second drive unit is spring-operated and has a drive unit spring, acting on the two drive connections associated with the second drive unit, wherein a drive unit controller is provided, which detects a predetermined deviation of the sensor signal of the movement sensor from a predetermined normal signal corresponding to the normal condition as an error condition and upon detecting an error condition carries out an error routine.

A method for the operation of a motorized flap arrangement of a motor vehicle, wherein the flap arrangement has a flap which is pivotable with respect to a motor vehicle body, wherein the flap arrangement has a back-driveable drive arrangement for the motorized adjustment of the flap and a control arrangement for controlling the drive arrangement. It is proposed that an, in particular gravitationally induced, predetermined flap deflection is detected by means of the control arrangement from a de-energized intermediate position of the flap in a monitoring routine and, in response to the detection of the predetermined flap deflection, a holding routine is triggered in which the drive arrangement is adjusted to a flap-holding position in a holding control circuit.

A door swing control device comprises a bracket affixed to a door, a pivoting element pivotably affixed to the bracket, and a swinging catch mechanism mounted directly or indirectly to the structure. The pivoting element comprises a finger extending therefrom and is engaged with the bracket to limit a range of movement of the pivoting element relative to the bracket. The finger is engageable with the swinging catch mechanism to limit a range of movement of the pivoting element relative to the swinging catch mechanism and thereby selectively limiting a range of movement of the bracket relative to the swinging catch mechanism. When the finger of the pivoting element is engaged with the swinging catch mechanism, the door is held in the first open position. When the finger of the pivoting element is disengaged from the swinging catch mechanism, the door can swing between the first and second open positions.

A drive arrangement for a motor vehicle flap including a gas pressure element, the gas pressure element has an outwardly sealed cylinder and a piston moveable in the cylinder interior along the cylinder axis and subdivides the cylinder interior into two sub-chambers, the gas pressure element has a first drive connection connected to the cylinder, and a second drive connection connected to the piston, the cylinder filled with a fluid and the piston has an overflow channel arrangement to create a balancing flow between the two sub-chambers to balance a pressure drop between the two sub-chambers. The piston is assigned a switchable valve arrangement which, depending on the pressure drop between the two sub-chambers, to create different through-flow states differing the cross section of the overflow channel arrangement. Upon exceeding a predetermined threshold for the pressure drop, the valve arrangement switches to change the cross section of the overflow channel arrangement.

A lifting apparatus (100) includes a connector assembly (110) with a first connecting member (120), a second connecting member (130) and a connecting link (140), the first and second connecting members (120, 130) configured to be pivot-mounted at first ends (122, 132) to a first stationary component (200), and a pneumatic supporting member (150) is coupled to the first and second connecting members (120, 130) via the connecting link (140). The connector assembly (110) and the pneumatic supporting member (150) are configured to perform a lifting motion, wherein, when performing the lifting motion, the first and second connecting members (120, 130) transition from a first position (P1) to a second position (P2) and the pneumatic supporting member (150) transitions from an extended position (EP) to a compressed position (CP).
