Second end 46.As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 7, second lock 30 and first lock tongue 28 can be common seam (not labeled)
It is sewn onto lap belt 26.First lock 24 and the second lock 30 can be identical material or different materials.For example, the first lock
24 and second lock 30 can be steel, aluminium or any suitable material.
First lock 24 may include slit 36 and release button 38, and the second lock 30 may include slit 40 and release by
Button 42.First lock 24 slit 36 may be designed to receive lock tongue 28, for example, lock tongue 28 and first lock 24 can lock tongue 28 with
Slit 36 operates in the engaged condition when engaging.When the first lock tongue 28 and the first lock 24 are in engagement state such as two point form seat
When seat belt configuration or three-point seat belt configure, lap belt 26 can extend to the first lock from waist expansion bend 20
Button 24.The release button 38 of first lock 24 can discharge the first lock tongue 28 from the slit 36 of the first lock 24, for example, release button
38 can be spring-loaded, as known.
The slit 40 of second lock 30 may be designed to receive the second lock tongue 34, for example, the second lock tongue 34 and the second lock 30
It can be operated in the engaged condition when the second lock tongue 34 is engaged with slit 40.The release button 38 of lock 24 can be discharged from slit 36
Lock tongue 28, and the release button 42 of the second lock 30 can discharge the second lock tongue 34 from slit 40.When the second lock tongue 34 and second
When lock 30 is configured in engagement state such as three-point seat belt or shoulder clasps configuration, shoulder safety belt 32 can be from shoulder
Portion's expansion bend 22 extends to the second lock 30.The release button 42 of second lock 30 can be from the release of slit 40 the of the second lock 30
Two lock tongues 34, for example, release button 42 can be spring-loaded, as known.
Belt assembly of seat 18 includes the first lock tongue 28 fixed to lap belt 26.For example, the first lock tongue 28 can
Second end 46 fixed to lap belt 26.First lock tongue 28 can be sutured in any suitable manner, welds, be fastened
Fixed to lap belt 26.First lock tongue 28 can be releasably engaged with the first lock 24.For example, the first lock tongue 28 and first
Lock 24 can operate under engagement state and disengaged position.In the engaged condition, as shown in fig. 4 to fig. 6 and Fig. 8, the first lock tongue
28 and 24 limitation lap belts 26 of the first lock 24 be pulled away from from the first lock.In a disengaged condition, such as Fig. 1 to Fig. 3 and Fig. 7
Shown, the first lock tongue 28 is spaced apart with lock 24, and lap belt 26 moves freely through and leaves the first lock 24.
Belt assembly of seat 18 includes the second lock tongue 34 fixed to shoulder safety belt 32.For example, the second lock tongue 34 can
Second end 50 fixed to shoulder safety belt 32.Second lock tongue 34 can be sutured in any suitable manner, welds, be fastened
Fixed to shoulder 32.Second lock tongue 34 can be releasably engaged with the second lock 30.For example, the second lock tongue 34 and the second lock 30
It can be operated under engagement state and disengaged position.In the engaged condition, as shown in Figure 6 and Figure 7, the second lock tongue 34 and the second lock
30 limitation shoulder safety belts 32 are pulled away from from the second lock 30.In a disengaged condition, as shown in Figures 2 to 4, the second lock tongue 34 with
Second lock 30 is spaced apart, and shoulder safety belt 32 moves freely through and leaves the second lock 30.First lock tongue 28 and the second lock
Tongue 34 can be formed by identical material or different materials.For example, the first lock tongue 28 and the second lock tongue 34 can be by steel, aluminium or any suitable
Material formed.
As noted previously, as both the first lock tongue 28 and the second lock 30 are fixed to lap belt 26, therefore first
Lock tongue 28 and the second lock 30 move together as a whole, thus allow easily accessible and operation lap belt 26, and
And it is easy to cooperate with the second lock tongue 34 and shoulder safety belt 32.Second lock 30 can be in lap belt 26 and first lock tongue 28
