Abstract: An electric seat and an angle adjustment device thereof are provided. The angle adjustment device includes an inner toothed plate and an outer toothed plate engaging with each other, and an eccentric cavity formed therebetween. An eccentric ring completely occupying a positive eccentric region of the eccentric cavity is provided in the eccentric cavity. The eccentric ring has a first accommodating region and a second accommodating region along a circumferential direction. The angle adjustment device further comprises a driving component for driving rotation of the eccentric ring. A damping component is provided in the first accommodating region and/or the second accommodating region, and the damping component is in a compressed state during operation of the driving component. The damping component eliminates a useless stroke in the above operation, thereby eliminating an adjustment lag experienced by a passenger during reverse adjustment of a seat and backrest.

Abstract: An angle adjusting device is provided, which includes a ratchet, multiple sliders, an expansion and retraction mechanism, and a sliding groove plate. The ratchet is provided with n inner teeth; and m slider groups consisting of the multiple sliders include one base slider group and m?1 deflecting slider groups, where the outer teeth of the deflecting slider groups have an angular deflection about a central shaft of the ratchet with respect to the outer teeth of the base slider group, and the angular deflection is (Z+k/m)360/n degrees, and 1?k?m?1, and the expansion and retraction mechanism is capable of simultaneously push the multiple sliders to extend in radial directions. The outer teeth of different sliders can simultaneously abut against or be engaged with the inner teeth at different phases, thus achieving the stable securing and stepless adjusting of the ratchet position.

Abstract: A seat recliner and an oil collecting element can re-collect the lubricating oil between a friction pair to friction surfaces, so as to reduce the wear rate. The oil collecting element is fixedly connected with one component in a friction pair of the seat recliner. The oil collecting element has an end face facing towards the other component in the friction pair, and each of two ends of the end face is provided with a boss, so as to form an oil collecting gap in the middle of the end face. The side face of the boss is an oil guiding face, and is configured gradually closer to the center of the oil collecting gap from outside to inside.

Abstract: Described herein is a recliner regulating device comprising a locking cam, an unlocking cam with a thickness less than the locking cam, a ratchet gear, a coulisse and a return spring connected with a central shaft. The locking cam is connected with the unlocking cam. Sliders are connected with the unlocking cam and sliding grooves. A jacket is connected with the ratchet gear and the coulisse. The return spring is connected with the coulisse. The thickness of the locking cam and the unlocking cam may be respectively designed in terms of the stress applied thereon. Since the locking cam and the unlocking cam are separately produced, structure of the die is simplified and service life of the die is improved significantly. The locking cam and the unlocking cam may be manufactured by punch, which leads to a greater production efficiency.

Abstract: A kernel part of a kind of flat spring recliner includes four major sub-components Ratchet a ratchet gear piece, a cam unit, a return spring and cover. A better adjustment of the angle and a fold-flat of auto seat is achieved. The cam unit can be further divided into a runner plate, a slider piece, a locking cam and an unlocking cam which is placed in the lower sink of the geared piece. In, the upper circle thereof, two segments are geared in a symmetrical position. In the groove inside the runner plate, there are two-geared slider pieces fitted to engage with the ratchet gear tooth. The sliders are designed with bosses on the surface, which match with the kidney slots in the unlocking cam, and with self-locking side, which are driven by the self-locking side on the locking cam to move off center in translation.
