Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] To address the technical problem of low load transfer efficiency of seat belts in known aircraft seats, this application provides an aircraft seat with a seat belt. It should be noted that this aircraft seat with a seat belt is used, but not limited to, aircraft. For ease of explanation, this application only uses the application of the aircraft seat with a seat belt in an aircraft as an example. The principle of applying the aircraft seat with a seat belt to other types of passenger equipment is essentially the same as that applied to aircraft, and will not be elaborated upon here. The aircraft can be a low-altitude aircraft, such as an electric vertical takeoff and landing (EVTOL) aircraft.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an aircraft 10 according to one embodiment of the present application. The aircraft equipment includes a frame 200 and an aircraft seat 100 with a seatbelt. The aircraft seat 100 with a seatbelt is disposed on the frame 200. The aircraft seat 100 with a seatbelt can be used for passengers or other occupants.

[0027] See Figures 1 to 2 The aircraft seat 100 with seatbelts includes a seat frame 110 and a seat body 120. The seat frame 110 is connected to the frame 200. The seat frame 110 can be made of composite materials such as aluminum alloy and titanium alloy, which has the advantages of being lightweight and high-strength, meeting the lightweight requirements of low-altitude aircraft and other aircraft 10, while providing stable and reliable support. The seat frame 110 can be fixedly connected to the frame 200 or movably connected to the frame 200. The seat body 120 is located on the seat frame 110. The seat frame 110 provides support for the seat body 120. The seat body 120 has a seat side 121 and a back side 122 arranged opposite each other. The seat side 121 is used for occupants to sit on. The back side 122 can be used to install related accessories of the aircraft seat 100 with seatbelts. The seat body 120 includes a seat plate 123 and a backrest 124. The backrest 124 is bent to connect to the seat plate 123. The seat 123 provides support for the occupant's buttocks, thighs, etc. The backrest 124 provides support for the occupant's back, head, etc.

[0028] See Figure 1 and Figure 2The aircraft seat 100 with seatbelt also includes a life jacket pocket 191 and a headrest 192. The life jacket pocket 191 is located on the underside of the seat plate 123. The backrest 124 includes a backrest frame 1241 and a backrest cushion 1242. The backrest frame 1241 is connected to the seat plate 123. The backrest cushion 1242 is located on the front side of the backrest 124 to support the occupant. The headrest 192 is connected to the side of the backrest cushion 1242 opposite to the seat plate 123. The backrest frame 1241 has a boarding handle 193 on one side along its width direction, and a first hook 194 on the other side along its width direction. The first hook 194 can be used to hang daily necessities such as headphones. The backrest frame 1241 has a backrest shell 1243 on the side opposite to the backrest cushion 1242. A magazine pocket 1244 is formed at the end of the backrest shell 1243 near the seat plate 123. On the surface of the backrest frame 1241 opposite to the backrest cushion 1242, a second hook 195 is provided at the end opposite to the seat plate 123. The second hook 195 can be used to hang clothes, hats, etc.

[0029] In this embodiment, see Figure 3 and Figure 4 The aircraft seat 100 with a seatbelt also includes an adjuster 141 and a seatbelt assembly 150. One end of the adjuster 141 is movably connected to the seat body 120, and the other end of the adjuster 141 is used to connect to the seat frame 110. The seatbelt assembly 150 includes a buckle 151 and a lap belt 152. The buckle 151 is located on the seat side 121, one end of the lap belt 152 is connected to the buckle 151, and the other end of the lap belt 152 is connected to the adjuster 141.

[0030] Thus, by connecting the seatbelt assembly 150 to the adjustment member 141, at least a portion of the human load carried by the seatbelt assembly 150 can be transferred to the seat frame 110 through the adjustment member 141, thereby dispersing the human load carried by the seat body 120, improving the efficiency of human load transfer, optimizing the overall load-bearing capacity of the aircraft seat 100 with seatbelt, and improving the protection effect for the occupant. Therefore, the aircraft seat 100 with seatbelt in this embodiment can significantly improve the fall protection capability for the occupant by dispersing the human load of the occupant through the seatbelt assembly 150. The lap belt 152 can restrain and protect the occupant's waist and abdomen. In the face of daily protection and accidental working conditions, the lap belt 152 can transfer most of the human load to the adjustment member 141, and then to the seat frame 110. In addition, since a portion of the human load transmitted by the seatbelt assembly 150 is transferred to the seat frame 110 through the adjustment member 141, the human load borne by the seat body 120 can be reduced, thereby improving the protection effect for the seat body 120.

[0031] The aircraft seat 100 with seat belt in this embodiment can withstand the dynamic and static strength loads of CCAR23 and CCAR27 in actual application, and the safety protection provided to the occupants can meet the requirements of CTSO-C127c.

[0032] For ease of description, this embodiment defines a first direction X1, a second direction X2, and a third direction X3. The first direction X1 is generally parallel to the vertical direction, and the seat body 120 is movably disposed on the seat frame 110 along the first direction X1. The second direction X2 is generally parallel to the forward direction of the aircraft 10. The third direction X3 is generally parallel to the width direction of the aircraft seat 100 with seat belts.

[0033] In one embodiment, see Figure 3 The seat frame 110 includes two spaced-apart chair legs 114. There are two adjusting members 141: one adjusting member 141 connects to one side of the seat body 120 and the corresponding chair leg 114, and the other adjusting member 141 connects to the other side of the seat body 120 and the corresponding chair leg 114. There are two lumbar belts 152, each connected to a corresponding adjusting member 141. Thus, the two lumbar belts 152 work together to protect the occupant, improving the uniformity of the load transfer from the human body to the two chair legs 114 of the seat frame 110, thereby enhancing the occupant's protection.

[0034] In other embodiments, a single waist belt 152 may also be provided. Two adjusting members 141 are connected to each end of the waist belt 152. The waist belt 152 can secure the occupant through a telescopic structure.

[0035] In this embodiment, see Figure 4 and Figure 5 The adjusting member 141 includes a movable part 1411 and a first extension 1412. A first clearance hole 1235 is provided on the seat body 120. The movable part 1411 is located on the backrest side 122 and connects the seat body 120 and the seat frame 110. One end of the first extension 1412 is connected to the movable part 1411. The first extension 1412 passes through the first clearance hole 1235 and extends to the seating side 121 of the seat plate 123. The first extension 1412 connects to the lap belt 152. This reduces the space occupied by the adjusting member 141 on the backrest side 122. Furthermore, since the lap belt 152 is generally located on the seating side 121, the first extension 1412 can easily connect to the lap belt 152, thereby improving the assembly efficiency of the aircraft seat 100 with a seat belt. In addition, the first clearance hole 1235 can also limit the movement of the first extension 1412, reducing its potential for swaying and extension.

[0036] In one embodiment, see Figure 4The first extension 1412 has a protruding section 14121. The protruding section 14121 extends from the first clearance hole 1235 to the seating side 121. The cross-sectional area of ​​the protruding section 14121 gradually decreases in the direction away from the movable part 1411. The first fastener 1522 connects to the end of the protruding section 14121 away from the movable part 1411. In this way, the space occupied by the first extension 1412 on the seating side 121 can be further reduced, and the first fastener 1522 can be prevented from affecting the installation of other seat components. In addition, since most of the first extension 1412 is located on the back side 122, if the occupant tilts the lumbar belt 152 forward during the occupant's seating process, the first extension 1412 is limited by the seat body 120 and will not come out of the first clearance hole 1235, thereby ensuring the reliability of the connection between the lumbar belt 152 and the adjustment member 141.

[0037] In this embodiment, see Figure 6 The adjusting member 141 is connected to the seat body 120 via a first fastener 142 and a second fastener 143. Specifically, the movable portion 1411 of the adjusting member 141, facing away from the seat frame 110, is sequentially connected to the seat body 120 via the first fastener 142. The first extension portion 1412 of the adjusting member 141, near the seat frame 110, is connected to the seat body 120 via the second fastener 143. Thus, the first fastener 142 and the second fastener 143 reliably secure both ends of the adjusting member 141, ensuring the reliable connection between the adjusting member 141 and the seat body 120, and further improving the reliability of load transmission in the seat belt assembly 150.

[0038] In one embodiment, see Figure 4 The seat plate 123 includes a first plate 1232 and a second plate 1233. The second plate 1233 is bent and connected to the first plate 1232. The backrest 124 is connected to the end of the second plate 1233 opposite to the first plate 1232. A first clearance hole 1235 is provided at the connection between the first plate 1232 and the second plate 1233. During actual riding, the occupant's waist and abdomen usually roughly correspond to the connection between the first plate 1232 and the second plate 1233. By providing the first clearance hole 1235 at this location, the restraining effect of the lap belt 152 on the occupant's waist and abdomen can be ensured, thus guaranteeing the reliability of load transmission of the seat belt assembly 150.

[0039] Furthermore, regardless of whether the seat plate 123 and the backrest 124 are fixedly connected or rotatably connected, the first clearance hole 1235 located at the seat plate 123 can ensure the reliability of the connection between the waist belt 152 and the adjustment member 141.

[0040] In one embodiment, see Figure 4The waist belt 152 includes a first belt body 1521 and two first buckles 1522. The two first buckles 1522 are respectively connected to both ends of the first belt body 1521. One first buckle 1522 is detachably connected to a locking buckle 151, and the other first buckle 1522 is connected to an adjusting member 141. This facilitates the fixed connection between the waist belt 152 and the adjusting member 141. The connection between the first buckle 1522 and the locking buckle 151 secures the waist belt 152. The first buckles 1522 also facilitate the extension and retraction of the first belt body 1521 to meet the needs of different occupants.

[0041] The first fastener 1522 and the locking fastener 151 can be connected by various detachable methods such as snap-fit ​​or latching.

[0042] In this embodiment, see Figure 3 and Figure 4 The seat belt assembly 150 also includes a shoulder strap 153. One end of the shoulder strap 153 is connected to the buckle 151, and the other end of the shoulder strap 153 passes around the seat body 120 and is connected to the backrest 122. The shoulder strap 153 can further provide safety protection for the occupant.

[0043] In this embodiment, see Figure 3 The seat belt assembly 150 also includes a retractor 154. The retractor 154 is connected to the back side 122 of the seat body 120, and the shoulder strap 153 is connected to the retractor 154. The retractor 154 is used to retract or release the shoulder strap 153.

[0044] Specifically, the retractor 154 can be fixed to the backrest frame 1241. The retractor 154 can be an inertial drum. After the shoulder strap 153 is separated from the buckle 151, the retractor 154 can automatically retract the shoulder strap.

[0045] In one embodiment, the retractor 154 is fixedly connected to the second plate 1233 of the seat plate 123 to further ensure the load transmission effect of the shoulder strap 153.

[0046] In one embodiment, see Figure 3 The backrest 124 is provided with a second clearance hole 1245. The shoulder strap 153 passes through the second clearance hole 1245. One end of the shoulder strap 153 is connected to the buckle 151. The other end of the shoulder strap 153 is connected to the retractor 154.

[0047] In one embodiment, see Figure 3 and Figure 4The shoulder strap 153 includes a second strap body 1531 and a second buckle 1532. One end of the second strap body 1531 is connected to a retractor 154. The other end of the second strap body 1531 is connected to the second buckle 1532. The second buckle 1532 is used to detachably connect to the locking buckle 151. By connecting the second buckle 1532 to the locking buckle 151, the shoulder strap 153 can be fixed. The second buckle 1532 also facilitates the extension and retraction of the second strap body 1531 to meet the needs of different occupants.

[0048] In one embodiment, there are two shoulder straps 153 and two retractors 154. Each shoulder strap 153 is connected to a buckle 151 and a corresponding retractor 154. Thus, the two shoulder straps 153 can be independently wound or released, thereby improving protection for the occupant's shoulders and providing greater versatility.

[0049] The two shoulder straps 153 and two lap belts 152 can be configured as a four-point harness, meeting the requirements of the TSO-C114 technical standard. In other embodiments, the harness assembly 150 also includes a crotch strap. The crotch strap is located between the two lap belts 152, thereby configuring the harness assembly 150 as a five-point harness.

[0050] In this embodiment, see Figure 5 The seat frame 110 has a sliding groove 111. The sliding groove 111 extends along the first direction X1, and one end of the adjusting member 141 is slidably disposed in the sliding groove 111 along the first direction X1, while the other end of the adjusting member 141 is connected to the seat body 120. In this way, the sliding groove 111 allows the adjusting member 141 to have only the first direction X1 as its degree of freedom, thereby enabling accurate adjustment of the position of the seat body 120 along the first direction X1.

[0051] In one embodiment, see Figure 5 The slide 111 has an opening 1111, and the seat frame 110 has a protruding stop 112 at the opening 1111. The adjusting member 141 passes through the stop 112 along one side of the third direction X3 and is connected to the seat body 120.

[0052] In one embodiment, see Figure 5 and Figure 6Along the width direction (i.e., third direction X3) of the slide groove 111, the first extension 1412 extends along one side of the third direction X3 and connects to the waist belt 152. The adjusting member 141 also includes a second extension 1413. The second extension 1413 extends along the other side of the third direction X3, and the projection of the second extension 1413 along the second direction X2 is located on the seat frame 110. Through the cooperation of the first extension 1412 and the second extension 1413, they can cooperate with the movable part 1411 in the depth direction (i.e., second direction X2) of the slide groove 111, respectively serving to clamp the two stop parts 112 on both sides of the width direction of the slide groove 111, thereby improving the movement reliability of the adjusting member 141.

[0053] Furthermore, in the event of a fall, the seat belt assembly 150 will pull the adjuster 141 along the second direction X2. At this time, the first extension 1412 and the second extension 1413 can limit the adjuster 141, thereby ensuring the restraint protection of the occupant by the seat belt assembly 150 and ensuring that the human body load can be smoothly transmitted to the seat frame 110 through the adjuster 141.

[0054] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
