Technical Field

The invention relates to the technical field of an airline passenger seat, in particular to an airline passenger seat and a PED (Personal Electronic Device) support which can be adjusted in a telescopic and multidirectional mode.

Background

At present, the known airline passenger seats are rarely provided with PED supports, and even if the airline passenger seats are provided with PED supports, the PED supports have very simple structure, and only limited size adjustment and up-down angle adjustment of the PED supports can be realized.

Most of PED supports of the conventional aviation passenger seats are integrally arranged on functional parts of a backrest structure through a clamping groove, such as a small table board at the rear part of a backrest or a book and newspaper box. However, such PED stands have limitations on the size and angle of adjustment of the PED, and can only be adjusted up and down within a small range. The limited size results in poor applicability of PED scaffolds; the limited adjustment angle affects the comfort of the passenger viewing the PED, and the passenger may easily get tired if viewing the PED at an uncomfortable angle for a long time.

Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 to 8, in the present embodiment, a telescopic and multi-directionally adjustable PED support for an airline passenger seat comprises a fixed base 5, a support base 1, a first linkage, an outer cover 2, and a side card 3, wherein,

first link mechanism is including articulated first connecting rod 6 in proper order, second connecting rod 7 and third connecting rod 8 (hinge 11 through a constant moment between the link structure is articulated), link mechanism is used for realizing extension and the shrink of support base 1, first connecting rod 6 still passes through hinge 11 with fixed baseplate 5 and articulates mutually, fixed baseplate 5 is fixed in on the back 15 of air passenger seat (through the fix with screw), third connecting rod 8 passes through universal bearing 9 and links to each other with support base 1, support base 1's both sides are installed and are installed rather than scalable side cardboard 3 with adjustment support width, enclosing cover 2 is articulated with support base 1's lower extreme and can open and shut for it in order to open or close support base 1. The cover 2 is rotatable 180 deg. relative to the stand base 1.

Further, referring to fig. 3 to 6 in combination, the top end of the stand base 1 is also provided with an elastic positioning bead 4 for fixing the closed outer cover 2. The locking of the outer lid 2 is achieved by the provision of resilient retaining beads 4, which are arranged to close.

Further, referring to fig. 5, the third link 8 may be completely housed inside the second link 7; the second connecting rod 7 can be completely collected in the first connecting rod 6, so that the space of the bracket is saved.

Further, referring to fig. 4, the bottom end of the outer cover 2 is provided with a flange structure for bottom support of the PED. The both sides of side cardboard 3 also are equipped with flange structure in order to carry out spacing with the both sides of PED.

The side cardboard 3 can have multiple structure to realize scalable. Referring to fig. 7, the present embodiment proposes a specific structure: a second connecting rod mechanism for realizing the extension and contraction of the side clamping plate 3 is arranged on the bracket base 1, the second connecting rod mechanism comprises two fourth connecting rods 12 and a fifth connecting rod 13, wherein,
